Description

Technical Field

[0001] The present application relates to the technical field of printing presses, and in particular to a material receiving device of a printing press. Background Art

[0002] During the use of the printing press, the material receiving device is arranged at the end of the printing press and has the function of receiving the printed products.

[0003] The receiving device of the existing printing machine mainly delivers the printed products through the conveyor belt, and then receives the products through the platform or box to stack the printed products. If the receiving plane is close to the conveyor belt surface, the operator needs to frequently take the products so that the printed products can be stacked smoothly. If the receiving plane is far from the conveyor belt surface, the operator takes the products less frequently, but the lighter printed products may be disturbed by too much air during the falling process, and the heavier printed products may fall at too large an angle, and the stacked printed products may be impacted by the falling printed products, which may cause the printed products to fail to be stacked and scatter everywhere. Summary of the invention

[0004] The present invention aims to provide a material receiving device for a printing press, which can improve the smoothness of stacking printed products while reducing the frequency of operators taking out materials.

[0005] The present application provides a material receiving device for a printing press, which adopts the following technical solution: A material receiving device of a printing press, comprising: A feeding mechanism, comprising a frame and a conveyor belt, wherein the conveyor belt is transmitted on the frame and is used to transport printed products; A material receiving mechanism, comprising a workbench and a material receiving basket, wherein the workbench is close to the discharge end of the conveyor belt; the material receiving basket is placed on the workbench and has an inlet for printed matter to enter the material receiving basket; when the material receiving basket is loaded, the inlet is located on a side of the material receiving basket close to the conveyor belt, and at this time, the inner bottom wall of the material receiving basket is a material receiving platform for stacking printed matter; and A lifting mechanism is connected to the workbench and is used to drive the workbench to rise and fall so as to adjust the distance between the material receiving platform and the conveyor belt when the material receiving basket is being loaded.

[0006] By adopting the above technical solution, by combining the feeding mechanism, the receiving mechanism and the lifting mechanism, the distance between the receiving platform and the conveyor belt is automatically adjusted during the stacking of printed products. This can not only reduce the frequency of operators taking materials, but also reduce the problem of printed products being scattered due to the distance between the receiving plane and the conveyor belt. Even if the printed products in the receiving basket are impacted by the falling printed products and blocked by the receiving basket, the displacement of the lower receiving basket can be reduced, so that the printed products can be stacked smoothly. In addition, the adjustment of the distance between the receiving platform and the conveyor belt can also prevent the printed products from being damaged due to the large impact force of falling, thereby improving the quality and production efficiency of the printed products.

[0007] Optionally, the lifting mechanism includes a base, a support frame, a screw and a power source; the support frame is fixed on the base and extends vertically, and the support frame is arranged on opposite sides of the workbench; the screw is rotatably connected to the support frame, and the screw axis extends vertically; the power source is installed on the support frame and connected to the screw to drive the screw to rotate; the side of the workbench has a moving part threadedly sleeved on the screw.

[0008] By adopting the above technical solution, the power source can drive the screw to rotate, thereby driving the moving part on the screw to move along the axis of the screw, and then driving the workbench to move up and down.

[0010] By adopting the above technical solution, two material receiving baskets are arranged on the workbench, and an adjusting member is provided to enable the lifting mechanism to move along the distribution direction of the material receiving baskets, so that the two material receiving baskets can be used alternately. This design improves the continuous operation capacity of the material receiving device, reduces the waiting time, and further improves the production efficiency.

[0011] Optionally, the outer wall of the material receiving basket on one side opposite to the material inlet is rotatably connected with a running wheel, and the running wheel has at least two rows; the workbench is provided with a connecting ear, and the connecting ear is connected with an insert shaft; When the material basket is being loaded, one row of the running wheels abuts against the surface of the workbench, and one end of the insertion shaft can pass through the connecting ear and be coaxially plugged into the running wheel; when the conveyor belt exits the material basket, the material basket can rotate around the axis of the running wheel, so that all the running wheels abut against the surface of the workbench, and at this time the feeding port is located on the upper side of the material basket.

[0012] By adopting the above technical solution, by rotating the material receiving basket to a state where the feed port is facing upward, the vertical stacking of printed materials can be converted into a state where each printed material is against the inner bottom wall of the material receiving basket, thereby improving the stability of the printed materials in the material receiving basket when the material receiving basket is transported, and making it less likely that the printed materials will tip over when stacked vertically.

[0013] Optionally, the material receiving basket is equipped with a pulling mechanism, which includes a mounting seat, a rotating shaft, a pulling rod and a lifting handle; the mounting seat is installed at the edge of the material receiving basket close to the feed port, the rotating shaft is rotatably connected to the mounting seat, the pulling rod is connected to the rotating shaft, and the lifting handle is connected to one end of the pulling rod.

[0014] By adopting the above technical solution, through the cooperation of the lifting handle and the pulling rod, the operator can hold the lifting handle to pull the material receiving basket to move on the ground, thereby improving the convenience of transporting the material receiving basket.

[0015] Optionally, the frame is connected with a bracket, and the bracket has a limit rod whose length extends along the conveying direction of the conveyor belt; the pull rod is slidably arranged on the rotating shaft; When the feed port is located on a side of the material receiving basket close to the conveyor belt, the pull rod can be rotated to extend vertically, and the lifting handle is supported by the limit rod, so that a space for printed materials to pass through is formed between the bottom of the pull rod and the surface of the conveyor belt, and the pull rod is opposite to the feed port to block the feed port. At the same time, the material receiving basket is lifted or lowered relative to the pull rod.

[0016] By adopting the above technical solution, a bracket and a limit rod are arranged on the frame, which cooperate with the pull rod so that the pull rod can block the feed opening when the material basket rotates, so that the printed matter is not easily scattered from the feed opening.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-7 This application is described in further detail.

[0029] The present application embodiment discloses a material receiving device for a printing press. Figure 1 The material receiving device of the printing press includes a material feeding mechanism 1, a material receiving mechanism 2, a lifting mechanism 5 and an adjusting part 7.

[0030] The feeding mechanism 1 includes a frame 101 and a conveyor belt 102. The conveyor belt 102 is circulated on the frame 101, and one end of the conveyor belt 102 is a discharge end. The finished printed product is placed on the surface of the conveyor belt 102 and is transported by the conveyor belt 102 toward the discharge end.

[0031] The material receiving mechanism 2 includes a workbench 201 and a material receiving basket 202. The workbench 201 is in the shape of a square plate with a horizontal surface and is opposite to the discharge end of the conveyor belt 102. The length direction of the workbench 201 is parallel to the feeding direction of the conveyor belt 102, and the width direction of the workbench 201 is perpendicular to the feeding direction of the conveyor belt 102.

[0032] Reference Figure 1 and Figure 2The lifting mechanism 5 and the adjusting member 7 are used to drive the workbench 201 to move relative to the conveyor belt 102. The lifting mechanism 5 drives the workbench 201 to move up and down. The adjusting member 7 is connected to the lifting mechanism 5 and is used to drive the lifting mechanism 5 and the workbench 201 to move along the width direction of the workbench 201. The material receiving basket 202 is in the shape of a square basket with an opening on one side. The opening of the material receiving basket 202 is a material inlet 3 for the printed matter to enter.

[0033] When in use, there are two material receiving baskets 202 on the workbench 201, and the two material receiving baskets 202 are placed side by side on the workbench 201 along the width direction of the workbench 201, and the material inlet 3 of the material receiving basket 202 is located on the side of the material receiving basket 202 facing the conveyor belt 102. At the same time, the material discharge end of the frame 101 and the conveyor belt 102 is opposite to the material inlet 3 of one of the material receiving baskets 202, and at this time, the inner bottom wall of the material receiving basket 202 is a material receiving platform 4 for supporting printed products and supporting printed products gradually stacked upward.

[0034] When the material basket 202 is initially loaded, the lifting mechanism 5 drives the workbench 201 to move upward to the lower side of the material receiving platform 4 close to the conveyor belt 102. When the conveyor belt 102 is conveyed, the printed materials fall one by one from the discharge end of the conveyor belt 102 into the material basket 202. While the printed materials are stacked in the material basket 202, the lifting mechanism 5 drives the workbench 201 to move downward gradually so that the top of the stacked printed materials is always located on the lower side of the surface of the conveyor belt 102, and the falling distance of the printed materials in the material basket 202 is controlled so that the printed materials are not easily damaged when they fall into the material basket 202.

[0035] Reference Figure 1 and Figure 2 When the current material receiving basket 202 is loaded to a nearly full state, the adjusting member 7 drives the workbench 201 to move along its own width direction, so that the other empty material receiving basket 202 is opposite to the discharge end of the conveyor belt 102. At the same time, the lifting mechanism 5 drives the workbench 201 to move upward until the material receiving plane of the material receiving basket 202 is close to the conveyor belt 102 to continue loading materials into the other material receiving basket 202. The operator can then replace the full material receiving basket 202 with a new empty material receiving basket 202 on the workbench 201.

[0036] Since there is usually a certain gap between two adjacent printed materials when the printed materials are distributed on the conveyor belt 102, the process of moving the mobile workbench 201 to match the other material receiving basket 202 to the conveyor belt 102 can be carried out while the gap between two adjacent printed materials is transmitted to the discharge end of the conveyor belt 102, so as to realize continuous feeding of printed materials.

[0037] Reference Figure 1, wherein the lifting machine oil includes a base 51, a support frame 52, a screw 53 and a power source 54. The base 51 is placed on the ground, and the bottom surface of the base 51 is arrayed with balls (not shown in the figure) that rotate on the base 51 and abut on the ground at the same time. The support frame 52 is fixed on the base 51 and extends vertically in the upward direction. There are two support frames 52, and the two support frames 52 are distributed along the width direction of the workbench 201 and are respectively located on the opposite sides of the base 51. The screw 53 corresponds to the support frame 52 one by one, the axis of the screw 53 extends vertically, and the upper and lower ends of the screw 53 are respectively rotatably connected to the upper and lower ends of the corresponding support frame 52. The power source 54 is a motor installed on the top of the support frame 52, and corresponds to the support frame 52 one by one. The output end of the power source 54 is fixedly connected to the screw 53 so as to drive the screw 53 to rotate in the forward or reverse direction.

[0038] The workbench 201 is fixed with moving parts 6 protruding from the workbench 201 in a direction away from each other on opposite sides. The moving parts 6 are in a square block shape, and the moving parts 6 on both sides of the workbench 201 are respectively threadedly connected to two screw rods 53. The two power sources 54 drive the connected screw rods 53 to rotate synchronously, so as to drive the workbench 201 to move up and down in the vertical direction.

[0039] In this embodiment, the adjusting member 7 is a multi-stage electric telescopic rod, the seat of the adjusting member 7 is fixed on the ground, the telescopic end of the adjusting member 7 is fixed to the base 51, and the telescopic direction of the telescopic end of the adjusting member 7 is parallel to the width direction of the workbench 201. When the telescopic end of the adjusting member 7 is recovered into the seat of the adjusting member 7, the base 51 and the workbench 201 are driven to move to one of the material receiving baskets 202 and the discharge end of the conveyor belt 102. When the telescopic end of the adjusting member 7 is fully extended, the base 51 and the workbench 201 are driven to move to the other material receiving basket 202 and the discharge end of the conveyor belt 102. When the base 51 moves, the ball rolls on the ground to reduce the friction between the base 51 and the ground.

[0040] Reference Figure 2 and Figure 3 Furthermore, a plurality of running wheels 8 are rotatably connected to the outer wall of the material receiving basket 202 on the side opposite to the material inlet 3, and the running wheels 8 are distributed in at least two rows along the length direction of the material receiving basket 202, and each row has at least two running wheels 8. Specifically, in the present embodiment, the running wheels 8 have two rows, and each row has two running wheels 8, and the two rows of running wheels 8 are respectively installed at two ends of the material receiving basket 202 away from each other.

[0041] When the material basket 202 is placed on the workbench 201 in a loaded state, that is, the feed inlet 3 is located at the side of the material basket 202, the outer periphery of one row of running wheels 8 also abuts against the surface of the workbench 201. When the material basket 202 is loaded, the material basket 202 is rotated along the axis of the running wheels 8 abutting against the surface of the workbench 201 to flip downward, so that all the running wheels 8 on the material basket 202 abut against the surface of the workbench 201. At this time, the feed inlet 3 of the material basket 202 is located on the upper side of the material basket 202. In this state, the material basket 202 is taken off the workbench 201 and placed on the ground, so that the running wheels 8 can be driven to roll on the ground by pushing and pulling the material basket 202, so as to drive the material basket 202 to move, thereby improving the convenience of transporting the material basket 202.

[0042] Reference Figure 3 and Figure 4 In order to improve the stability of the material receiving basket 202 on the workbench 201, connecting ears 23 are fixed on the two opposite sides of the workbench 201, and a space for placing two material receiving baskets 202 is formed between the connecting ears 23 on both sides of the workbench 201, and a plug-in shaft 9 is threaded through the connecting ears 23, and a slot for plugging the plug-in shaft 9 is opened on the side of the body of the traveling wheel 8 on the material receiving basket 202. When the two material receiving baskets 202 are placed side by side, the material receiving basket 202 is moved to a position close to the connecting ears 23, so that the slot on the traveling wheel 8 is opposite to the plug-in shaft 9, so that the plug-in shaft 9 can be inserted into the slot by moving the plug-in shaft 9 through the thread, so that the plug-in shaft 9 is coaxial with the wheel body of the traveling wheel 8, thereby limiting the movement of the material receiving basket 202 on the workbench 201 along the feeding direction and improving the stability of the material receiving basket 202. In addition, when the material basket 202 is turned over after loading, the material basket 202 rotates axially around the insertion shaft 9, and the walking wheel 8 is limited by the insertion shaft 9 to improve the stability of the material basket 202 during rotation.

[0043] Reference Figure 5 and Figure 6 Furthermore, a pulling mechanism 11 for assisting in pulling the material basket 202 is installed on the material basket 202. The pulling mechanism 11 includes a mounting seat 111, a rotating shaft 112, a pull rod 113, and a lifting handle 114. The mounting seat 111 includes two mounting ears 1111, and the two mounting ears 1111 are both fixed to the edge line of one end of the material basket 202 near the material inlet 3. When the material basket 202 is in a loading state, the mounting ears 1111 are located at the upper part of the material basket 202.

[0044] The rotating shaft 112 is located between the two mounting ears 1111, and the two ends of the rotating shaft 112 that are far away from each other extend to the opposite side of the two mounting ears 1111, and the rotating shaft 112 can rotate relative to the mounting ears 1111 around the axis of the rotating shaft 112. The pull rod 113 is connected to the rotating shaft 112, and the lifting handle 114 is in the shape of a cross plate and fixed to one end of the pull rod 113. The pull rod 113 can drive the rotating shaft 112 to rotate, so that when the material receiving basket 202 is in an upward position with the feed port 3, the pull rod 113 rotates to extend upward in a direction away from the material receiving basket 202. The staff can pull the material receiving basket 202 to move by holding the lifting handle 114, further improving the convenience of moving the material receiving basket 202.

[0045] Reference Figure 2 and Figure 7 Furthermore, the pull rod 113 passes through the rotating shaft 112 and can slide relative to the rotating shaft 112 along the length direction of the pull rod 113, and the pull rod 113 is in the shape of a square rod. The side of the frame 101 is connected to a bracket 12 extending upward, and a limit rod 13 is fixed on the top of the bracket 12. The length extension direction of the limit rod 13 is parallel to the width direction of the workbench 201.

[0046] When the material basket 202 is in the loading state and the insertion shaft 9 is inserted into the walking wheel 8, the pull rod 113 can be rotated to a state where the length is extended vertically, and the lower surface of the lifting handle 114 abuts against the upper surface of the limiting rod 13, and the bottom end of the pull rod 113 is opposite to the surface of the conveyor belt 102. When the workbench 201 moves to the top of the screw 53 and the material receiving platform 4 is close to the conveyor belt 102, there is a space between the bottom end of the pull rod 113 and the surface of the conveyor belt 102 for the printed matter to pass through. When the workbench 201 gradually descends and drives the material basket 202 to gradually descend, the limiting rod 13 has a limiting effect on the lifting handle 114, and the pull rod 113 is positioned relative to the limiting rod 13. When the loading of the material basket 202 is completed, it is driven by the workbench 201 to move away from the position opposite to the conveyor belt 102, and when the workbench 201 rises, the lifting handle 114 is driven by the material basket 202 and moves along the width direction of the workbench 201 on the limiting rod 13. At this time, the pull rod 113 relatively blocks the feed openings 3 in the middle and upper parts of the material basket 202, so that when the material basket 202 is turned over, the printed materials stacked in the material basket 202 are not easily moved out from the feed opening 3 due to shaking, thereby improving the stability of the printed materials when the material basket 202 is turned over.

[0047] Reference Figure 6 and Figure 7In order to improve the stability of the pull rod 113, a limiting shaft 14 is slidably penetrated on one of the mounting ears 1111 along the axial position of the rotating shaft 112. The outer diameter of the limiting shaft 14 is smaller than the outer diameter of the rotating shaft 112, and one end of the limiting shaft 14 is coaxially inserted into the rotating shaft 112 and is located on one side of the mounting ear 1111. The other end of the limiting shaft 14 extends away from the rotating shaft 112 from the other side of the mounting ear 1111 and is fixed with a handle 17. The handle 17 is in the shape of a disc coaxial with the limiting shaft 14, and the outer diameter of the handle 17 is larger than the outer diameter of the limiting shaft 14. A stop portion 19 is fixed on the inner wall of the mounting ear 1111 and protrudes inward from the inner wall of the mounting ear 1111. A stop groove 20 is provided on the outer wall of the limiting shaft 14 for the stop portion 19 to be pressed into. The stop groove 20 extends in a direction parallel to the axial line of the limiting shaft 14 to guide the moving direction of the limiting shaft 14 and at the same time limit the rotation of the limiting shaft 14 relative to the mounting ear 1111.

[0048] The limiting block 15 is fixed to one end of the limiting shaft 14 located in the rotating shaft 112. The limiting block 15 is in a square structure, and the outer circumference of the limiting block 15 does not exceed the outer circumference of the rotating shaft 112. A sliding groove 16 is provided on the side wall of the pull rod 113 for the limiting block 15 to push into, and the sliding groove 16 extends along the length direction of the pull rod 113. An elastic member 18 is connected between the handle 17 and the mounting ear 1111. The elastic member 18 is a spring coaxially sleeved on the limiting shaft 14, and the opposite ends of the spring are respectively connected to the handle 17 and the mounting ear 1111.

[0049] When the rotation-limiting block 15 is located outside the chute 16, the spring gives elastic force to the handle 17 to move toward the pull rod 113. When the rotation-limiting block 15 is pressed into the chute 16, the spring is in a natural state, and at this time, the material receiving basket 202 is moved to the loading state, the pull rod 113 extends vertically, and when the pull rod 113 moves up and down relative to the rotating shaft 112, the rotation-limiting block 15 slides in the chute 16 to guide the movement of the pull rod 113, thereby improving the stability of the movement of the pull rod 113.

[0050] When the pull rod 113 needs to be rotated to a state where it is tilted and extended relative to the material receiving basket 202, the handle 17 is held to pull the limit shaft 14 outward to move the limit block 15 out of the slide groove 16, so as to push the pull rod 113 so that the rotating shaft 112 and the pull rod 113 can rotate relative to the mounting ear 1111.

[0051] Reference Figure 6 and Figure 7In addition, a stopper 21 is fixed to one end of the pull rod 113 away from the lifting handle 114, and the stopper 21 has a portion extending out of the side wall of the pull rod 113, so that the cross-sectional dimension of the stopper 21 along the length direction of the pull rod 113 is larger than the cross-sectional dimension of the pull rod 113 along its own length direction. A stopper groove 22 is provided on one side of the rotation shaft 112 facing the stopper 21, into which the stopper 21 is pressed, so as to prevent the pull rod 113 from being separated from the rotation shaft 112.

[0052] The implementation principle of a material receiving device of a printing press in the embodiment of the present application is as follows: a material receiving basket 202 is placed on a workbench 201 and limited by an insert shaft 9, and the workbench 201 is first driven by an adjusting member 7 to move to one of the material receiving baskets 202 close to and opposite to the discharge end of the conveyor belt 102, so that the printed matter enters the material receiving basket 202 for stacking when it moves out of the discharge end of the conveyor belt 102, and the lifting mechanism 5 drives the workbench 201 and the material receiving basket 202 to gradually move downward when the printed matter is stacked. When the material receiving basket 202 is fully loaded, another material receiving basket 202 is driven by the adjusting member 7 to be opposite to the conveyor belt 102, and at the same time, the lifting mechanism 5 drives the workbench 201 to move upward. The operator flips the full material receiving basket 202 so that the feed inlet 3 of the material receiving basket 202 is set upward, and then removes the material receiving basket 202 from the workbench 201 and replaces the empty material receiving basket 202.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
