Description

[0001] This case is a divisional application based on the invention patent with application date of October 31, 2017, application number 201711053873.9, and name “A method and device for automatic control of a paging machine” as the parent case. Technical Field

[0002] The present invention relates to the field of explosive production, in particular to a label paging application suitable for finished product packaging instructions of explosive production lines, specifically a label paging machine and a label paging method thereof. Background Art

[0003] In the finished product packaging process of the explosives production line, the stacked instruction labels are usually manually paged and loaded into each explosive box. This method is not only labor-intensive and inefficient, but also fails to meet the requirements of technological advancement in the industry.

[0004] To address the above problems, Wenzhou Lianteng Packaging Machinery Co., Ltd. has produced an automatic paging machine model LT-980. The device includes a photoelectric sensor, a counting controller, a feed wheel, a conveyor belt, a reversing wheel, a pair of upper auxiliary wheels, a paper discharge pressure roller, and a paper pressing plate. The photoelectric sensor is placed between the pair of upper auxiliary wheels and can automatically paginate. However, it has the following shortcomings: First, the photoelectric sensor is a special accessory and is installed close to the label conveying rotation mechanism, which is not convenient for repairing faults. Second, due to the conveying distance and the tightness of each roller, it is easy to cause the secondary label and the bottom label to overlap. That is, when the device conveys the bottom label through the feed wheel, the secondary label is also conveyed forward one after the other, overlapping with the bottom label. After the bottom label passes the sensor sensing position, the secondary label remains at the sensing position. At this time, the sensor is equivalent to sensing only a single label passing signal. The conveying motor will continue to drive the feed wheel to rotate, continuously conveying the secondary label forward until the secondary label leaves the sensing position and stops rotating. This causes multiple pages to appear, which sometimes causes the machine to jam, causing current overload, and even damage to the circuit board.

[0005] Therefore, designing an automatic control device for a paging machine seems to have practical significance. Summary of the Invention

[0006] The technical problem to be solved by the present invention is: In response to the above problems, the present invention provides a label paging machine and a label paging method thereof, the process technology and method of which are simple and reliable, which can not only improve the stability of the operation of the entire control device, but also reduce the cost of replacing spare parts and the workload of equipment maintenance and repair, thereby ensuring the normal operation of production.

[0007] The present invention provides a label paging machine and a label paging method thereof. The paging machine automatic control device includes a transmission motor, a first photoelectric sensor and a second photoelectric sensor disposed on the right side of a finished carton conveyor belt, an instruction label, a paper box, a counting controller, a feed wheel, a conveyor belt, a reversing wheel, a pair of upper auxiliary wheels, a paper discharge pressure wheel, and a paper pressing plate. The brake system of the paging machine automatic control device is a commonly used simple small component consisting of a rectangular stainless steel plate with a thickness of 2 mm, a screw, and a plurality of metal gaskets under the steel plate. The left side of the stainless steel plate is fixed to the paging machine mechanism by a screw. The height difference between the loose gasket and the right side of the stainless steel plate is adjusted by squeezing the steel plate with the screw to achieve the height difference between the loose gasket and the right side of the stainless steel plate. The minimum height of the right side of the stainless steel plate should be adjusted to between the thickness of one label sheet and the thickness of two label sheets. When a secondary label and a bottom label overlap, the brake system ensures that the bottom label can pass smoothly. Since the thickness of the two overlapping labels is greater than the minimum distance between the stainless steel plate and the bottom label, the stainless steel plate will hinder the secondary label from continuing to move forward, thereby acting as a brake.

[0008] The second photoelectric sensor of the device is moved from between a pair of upper auxiliary wheels and the paper discharge pressure wheel to the rear end of the paging machine conveying rotation mechanism; the added brake system is placed at the rear end of the paper discharge pressure wheel.

[0009] Before work, adjust the brake system first. By adjusting the number of left and right gaskets, there is a certain height difference between the left and right gaskets. Then, by adjusting the tightness of the screws, squeeze the stainless steel plate so that the left and right sides reach the height difference of the loose and tight gaskets. After repeatedly adjusting the height difference, when the lowest height of the right side of the stainless steel plate from the conveying surface is between the thickness of one label paper and the thickness of two label papers, the adjustment of the brake system is completed.

[0010] During operation, a stack of instruction labels is neatly placed into a carton. The run button on the counter controller control panel is pressed to power the system. When the No. 1 photoelectric sensor on the finished product conveyor belt senses a carton passing by, the counter controller is reset, the paging machine drive motor starts, driving the feed wheel and conveyor belt to rotate, and paging is performed through the reversing wheel. After being guided and pulled by a pair of upper auxiliary wheels and the paper output pressure roller, and guided by the cardboard, the first instruction label is output. After the tail end of the label passes through the sensing range of the No. 2 photoelectric sensor, it falls into the carton and the second instruction label is output at the same time. When the No. 2 photoelectric sensor on the automatic paging machine senses the front end of the second instruction label, if the No. 1 photoelectric sensor receives a signal that the second carton has passed, the paging machine drive motor continues to run and feeds the label into the second carton. If the No. 1 sensor 1 does not receive a signal that the second carton has passed at this time, the paging machine motor stops running and the second instruction label is on standby. This constitutes one action cycle. The brake system is located at the rear end of the paper output roller. It has no braking effect on the bottom label that is as thick as a sheet of paper. When the second-layer label overlaps with the bottom label, the brake system will prevent the second-layer label from moving forward. After the rear end of the bottom label passes the sensing position, the second-layer label will still stay in front of the sensing position of the No. 2 photoelectric sensor. At this time, the paging motor will stop rotating to prevent multiple pages from occurring.

[0011] The advantages of the present invention are: effective automatic paging, stable production operation, and low equipment failure rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0018] The present invention will be further described in detail below with reference to the specific embodiments of the drawings.

[0019] As shown in the figure:

[0020] The label paging machine includes a transmission motor, a No. 1 photoelectric sensor and a No. 2 photoelectric sensor arranged on the right side of the finished carton conveyor belt, an instruction label, a paper box, a counting controller, a feed wheel, a conveyor belt, a reversing wheel, a pair of upper auxiliary wheels, a paper discharge pressure wheel, and a paper pressing board. It also includes a brake system, a brake system of the paging machine automatic control device, which is a commonly used simple small component composed of a rectangular stainless steel plate with a thickness of 2mm, a screw and several metal gaskets under the steel plate. The left side of the stainless steel plate is positioned on the paging machine mechanism with a screw. The height difference between the loose gasket and the steel plate is achieved by squeezing the steel plate with the screw to adjust the minimum height of the right side of the stainless steel plate from the conveying surface. The minimum height of the right side of the stainless steel plate should be adjusted to between the thickness of one label paper and the thickness of two label papers. When the sub-layer label and the bottom label overlap, it can ensure that the bottom label passes smoothly. Since the thickness of the two overlapping labels is greater than the minimum distance of the stainless steel plate, the stainless steel plate will hinder the sub-layer label from continuing to move forward, thus acting as a brake.

[0021] The second photoelectric sensor of the device is moved from between a pair of upper auxiliary wheels and the paper discharge pressure wheel to the rear end of the paging machine conveying rotation mechanism; the added brake system is placed at the rear end of the paper discharge pressure wheel.

[0022] Before work, adjust the brake system first. By adjusting the number of left and right gaskets, there is a certain height difference between the left and right gaskets. Then, by adjusting the tightness of the screws, squeeze the stainless steel plate so that the left and right sides reach the height difference of the loose and tight gaskets. After repeatedly adjusting the height difference, when the lowest height of the right side of the stainless steel plate from the conveying surface is between the thickness of one label paper and the thickness of two label papers, the adjustment of the brake system is completed.

[0023] During operation, a stack of instruction labels is neatly placed into a carton. The run button on the counter controller control panel is pressed to power the system. When the No. 1 photoelectric sensor on the finished product conveyor belt senses a carton passing by, the counter controller is reset, the paging machine drive motor starts, driving the feed wheel and conveyor belt to rotate, and paging is performed through the reversing wheel. After being guided and pulled by a pair of upper auxiliary wheels and the paper output pressure roller, and guided by the cardboard, the first instruction label is output. After the tail end of the label passes through the sensing range of the No. 2 photoelectric sensor, it falls into the carton and the second instruction label is output at the same time. When the No. 2 photoelectric sensor on the automatic paging machine senses the front end of the second instruction label, if the No. 1 photoelectric sensor receives a signal that the second carton has passed, the paging machine drive motor continues to run and feeds the label into the second carton. If the No. 1 sensor 1 does not receive a signal that the second carton has passed at this time, the paging machine motor stops running and the second instruction label is on standby. This constitutes one action cycle. The brake system is located at the rear end of the paper output roller. It has no braking effect on the bottom label that is as thick as a sheet of paper. When the second-layer label overlaps with the bottom label, the brake system will prevent the second-layer label from moving forward. After the rear end of the bottom label passes the sensing position, the second-layer label will still stay in front of the sensing position of the No. 2 photoelectric sensor. At this time, the paging motor will stop rotating to prevent multiple pages from occurring.

[0024] The embodiment described above is only one of the preferred specific implementation methods of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
