Description

Paper tube automatic loading device

The present invention relates to an automatic paper tube loading device, and more particularly, automatic paper tube loading in which a plurality of paper tubes manufactured in the paper tube manufacturing process are sandwiched as a unit and transported and loaded in multiple stages without damage to the paper tubes on a loading trolley. It's about the device.

In general, paper tubes are manufactured by winding several sheets of paper strips in a spiral shape by a rotating belt in a twisted state. The paper tube cut to a certain length has a different weight depending on the thickness, length and diameter, so the larger the diameter and the longer the length, the greater the weight.

The paper tube manufactured in this way is transported to the loading place and loaded in a stacking method. The thicker the paper tube, the greater the length and diameter, the greater the weight. Not only does it cause pain, but it also takes a long time to work, so the work efficiency is low, and usually two or more workers need to lift it together, so a lot of manpower is required.

Republic of Korea Patent Registration No. 10-1295334, devised as a method to solve this problem, solves the problem of conventional workers lifting and transporting the paper tube by transporting and loading the paper tube based on the paper tube transfer unit, but it moves the paper tube to a high position. In the process of moving and falling while the paper tube rotates along the inclination of the paper tube transfer part, the breakage of the paper tube occurs due to the collision between the impact and the paper tube. In particular, when loading in multiple stages, the first transfer unit and the second transfer unit must be loaded by lifting them around the hinge, so the structure is complicated. There was a disadvantage in that the paper tube loading process, which had to move the placed paper tube back to the bogie, was inefficient.

An object of the present invention is to solve the above problems, and it is an automatic paper tube loading device that allows the paper tubes to be transported horizontally and a plurality of paper tubes are sandwiched as a unit so that they can be stacked in close contact with each other without damage to the bogie in multiple stages. is to provide

In addition, the inlet position sensor 10 is installed on one side of the upper body frame 9 of the conveyor belt 3 to detect when the branch pipe P reaches the correct position due to the rotation of the conveyor belt 3 to detect it. The rotation of (3) is temporarily stopped.

This is a state in which the paper tube (P), which is descended along the guide plate (1), is straightly aligned on the support plate (7) at a predetermined position by transferring the paper tube (P) in a certain direction by the rotation of the conveyor belt (3). to be transported to

In the paper pipe manufacturing line, the paper pipe P, which is cut to a certain length and descended along the guide plate 1, comes into contact with the blocking plate 2 and is transported by the rotation of the conveyor belt 3 at the same time and reaches the correct position when it reaches the correct position. The sensor 10 detects this and turns off the motor 4, thereby temporarily stopping the rotation of the conveyor belt 3, and at the same time, the centering cylinder 8 is operated to draw in the piston rod 5, and the branch pipe supply device ( 100) The assembly is rotated 90° to center the paper tube (P) on the conveyor belt (3) on the side support plate (7) and then the paper tube feeder (100) is returned to its original position to operate continuously. The paper pipe (P) transferred to the support plate (7) rolls along the inclination of the support plate (7) and is placed one after another. of the branch pipe ascending and descending transfer stage.

The branch pipe lifting and transporting device 200 is a device that simultaneously grips one unit of the branch pipe (P) transferred through the above-described process and transfers it to the bogie 300 together with the lift, which can accommodate a plurality of branch pipes (P).

The pair of opposing gripper plates 12 and 12 ′ are left and right screws and left screws of a screw tube body 19 in which a plurality of guide rods 18 protruding outside are crossed in the middle of the bottom of the rectangular frame 11 . It is screwed to the nut pipe 20, which is moved inward or outward at the same time, and is installed in a penetrating state in a state of being resilient with a spring 22.

Accordingly, when a plurality of paper tubes P are arranged on the support plate 7 after being transferred from the paper tube supply device 100, the counter sensor 23 detects the set number of paper tubes P and turns on the clamping motor 24. Due to this, when the screw is rotated, the nut tube 20 coupled thereto simultaneously moves the bracket 21 while moving inward or outward at the same time. The clamping plates 12 and 12', which are installed as , are in close contact with both sides of the branch pipe (P) and are clamped or spaced apart.

The left and right clamp sensors 25 installed in the bracket 21 detect the distance from the gripper plates 12 and 12' while the gripper plates 12 and 12' are pinching both ends of the branch pipe P. Thus, by turning off the clamping motor 24, a constant and appropriate clamping is possible, and the release of the clamping force is detected by the lowering stop sensor 26 in the process of being lowered to load the paper tube P on the bogie 300. The nut tube 20 is moved outward by the reverse rotation of the clamping motor 24 and the opposite rotation of the screw with the lowering stop. At this time, the outer movement of the nut tube 20 is a product length adjustment sensor installed at the top As the clamping motor 24 is turned off according to the detection of (27), it is stopped at the set position.

In addition, the rectangular frame 11 is connected to the elevating motor 13 and the chain 14 installed on the traveling table 17 to elevate and elevate by winding and unwinding of the chain 14 by the elevating motor 13, , A plurality of horizontal holding rods 28 are installed for lifting and lowering the rectangular frame 11 to a stable and balanced state, and a rising stop sensor 29 and a falling stop sensor 26 are installed on one side of the upper and lower sides. .

Therefore, when the number of paper tubes (P) set on the support plate (7) are placed in a row, the counter sensor (23) is firmly held on both sides by the front and rear clamping plates (12, 12') to detect the paper tube (P). As the chain 14 is wound by the operation of the elevating motor 13, the rectangular frame 11 with the branch pipe P is lifted so that the next loading step can be performed.

In this way, when the rectangular frame 11 holding the branch pipe P is raised by winding of the chain 14 by the clamping motor 24, the bogie 300 along the rail 15 installed on the upper part of the body frame 9. It is transported to the pole to load the branch pipe (P), and the elevating motor 13 and the horizontal holding rod 28 connecting the rectangular frame 11 with a chain 14 are installed on the traveling table 17 and installed on the traveling table. (17) and the rectangular frame (11) are reciprocated at the same time.

A traveling motor 16 is installed in front of the traveling table 17, and a pulley 31 is installed on the bottom thereof to advance along the rail 15 installed in the body frame 9, and the upper side of the cart 300 A forward low speed sensor 32 and a stop sensor 33 are installed at the tip of the rail 15 located at A reverse stop sensor 34 is installed at the rear end of the rail 15 so as to stop at the original position when moving backward.

The branch pipe lifting and transporting device 200 is a state in which a plurality of unit branch pipes (P) centered and arranged in a row from the branch pipe supply device 100 are sandwiched by the clamping plates 12 and 12' of the rectangular frame 11. The chain 14 is raised to the upper part of the bogie 300 by the winding operation of the chain 14 and advanced together with the running table 17 that slides along the rail 15 by the operation of the traveling motor 16, and the interposed branch pipe P (300) When it is located on the upper part, it is stopped based on the stop sensor 33 and at the same time the elevating motor 13 is operated to unwind the wound chain 14 and lower the rectangular frame 11 to the inside of the bogie 300, and the rectangular frame body When the descending stop sensor 26 installed in (11) detects the gap with the branch pipe (P) inside the bogie 300, the clamping motor 24 reverses rotation to relax the gripper plates 12 and 12'. By separating it from the paper tube (P), the entire paper tube (P) of one unit for which the clamping force is released is loaded in an accurate and aligned state one by one on the upper part of the previously loaded paper tube (P).

The bogie 300 has a plurality of separation prevention rods 36 built on the outside with wheels 35 so that the paper tube P can be loaded at a certain height, and the paper tube P is loaded at the rear of the bogie 300. Upon completion, a take-out device 400 composed of three take-out cylinders for pushing and taking out the bogie 300 from the main body is installed.

The bogie 300 is locked by the locking cylinder 37 during the loading operation to prevent flow, and when the loading is completed, the locking cylinder 37 is released to enable extraction by the take-out device 400 .

The ejection device 400 is installed on both sides of the primary ejection cylinder 38 and the bogie 300 that directly pushes the middle of the bogie 300, and is installed on both sides of the base plate 38 ′ of the primary ejection cylinder 38 . It is composed of two secondary blow-out cylinders 39 that push the .

Therefore, when a plurality of paper tubes (P) of one unit transferred by being sandwiched by the gripping plates 12 and 12' are completed loading on the bogie 300, the loading completion sensor 40 installed in the body frame 9 detects this and By applying a signal to the ejection device 400, the primary ejection cylinder 38 and the secondary ejection cylinder 39 are simultaneously operated, but the primary ejection cylinder 38 directly pushes and ejects the bogie 300, and at the same time The secondary take-out cylinder 39 pushes the base plate 38' of the take-out cylinder 38 to completely take out the bogie 300 from the main body.

The entire operating process of the present invention configured as described above will be described in stages as follows.

First, when the paper tube (P) produced from the paper tube production device is cut to a certain length and descends along the guide plate 1, it collides with the blocking plate 2 of the paper tube supply device 100 and the conveyor belt 3 is rotating at the same time. When it is moved in one direction by the and is detected by the incoming position sensor, the rotation of the conveyor belt (3) is temporarily stopped and the centering cylinder (8) is operated at the same time as the blocking plate (2) and the conveyor belt (2) around the shaft (6). 3) By rotating the entire assembly by 90°, the paper tube (P) is transferred by centering to the support plate (7) of the branch tube lifting and transporting device (200) on the side.

When the paper tube (P) is continuously arranged on the support plate (7) and the counter sensor (23) detects a set number, a pair of front and rear facing fingers installed in the rectangular frame (11) of the paper tube lifting and lowering transfer device (200) As the plates 12 and 12' move inside the nut tube 20 and the bracket 21 according to the screw rotation by the clamping motor 24, the both ends of the branch pipe P are firmly clamped. At this time, the bracket ( Since a spring 22 is installed in the guide rod 18 of the gripper plates 12 and 12' passing through 21), when the grippers 12, 12' are in close contact with both ends of the branch pipe P The bracket 21 is pinched while compressing the spring 22 to enable more powerful gripping. When the installed left and right clamp sensors 25 detect the set gap with the clamping plates 12 and 12', the clamping motor 24 is turned off to stop the rotation of the screw. do.

As such, when the clamping motor 24 is turned off, the lifting motor 13 is then operated to lift the rectangular frame 11 upward while winding the chain 14, and the set height (a position higher than the separation prevention interval 36) ), the rising stop sensor 29 detects this and stops the ascent, and at the same time the traveling motor 16 operates to advance the traveling table 17 along the rail 15, and the traveling table 17 has a rectangular frame. Since the sieve chain 14 and the rectangular frame 11 holding the branch pipe P with the horizontal holding rod 28 are integrally installed, the traveling table 17 and the rectangular frame 11 move forward at the same time to the upper part of the loading device. is decelerated by the forward low-speed sensor 31 installed at the tip of the rail 15 in the while the branch pipe (P) of one unit sandwiched between the clamping part is lowered inside the bogie 300, and when the previously loaded branch pipe (P) is detected by the detection of the lowering stop sensor 26, the clamping motor 24 is reversed. The gripping force is released as the gripping force is released by rotating the gripping plates 12 and 12' in an operation opposite to the gripping process described above. are gradually loaded.

When the loading is completed in this way, the clamping motor 24 is turned off as the product length adjustment sensor 27 senses the product length adjustment sensor 27 in the process of opening the grippers 12 and 12 ', and at the same time, the chain ( 14) is rolled up to raise the rectangular frame 11, and then, the traveling table 17 is moved backward by the traveling motor 16, and the rectangular frame 11 is also returned to its original position, and the reverse is stopped by the reverse stop sensor 34. At the same time, the rectangular frame 11 is lowered by the operation of the lifting motor 13 to enter a series of waiting states for clamping the branch pipe P, and the same operation as described above is continuously repeated.

On the other hand, when the loading of the branch pipe (P) in the cart 300 is completed to the set height, the loading completion sensor 40 detects this and the locking cylinder 37 holding the cart 300 together with the buzzer is released and the take-out device ( 400), the extraction operation is performed.

The take-out device 400 is installed on both sides of the primary take-out cylinder 38 and the bogie 300 that directly pushes the middle of the bogie 300 to remove both sides of the base plate 38' of the primary take-out cylinder 38. Since it is composed of the secondary ejection cylinder 39 that pushes, when the bogie 300 is taken out, the primary ejection cylinder 38 pushes the middle of the bogie 300 and pushes it out as a whole, and at the same time the bogie can be taken out in a balanced state. Since the secondary take-out cylinder 39 pushes both sides of the 300, the bogie 300 is taken out of the main body by the take-out device 400 in a stable state, thereby completing the paper tube loading process of one cycle.

When this series of processes is completed, the continuous paper pipe loading operation can be efficiently performed by placing a new bogie 300 and repeating the same process as in the previous section. Because a large number of paper (P) pipes can be loaded in an aligned state with a simple process, the loading time is fast, the structure is simple, and it is easy to put into practical use.
