Description

Technical Field

[0001] The utility model relates to a paging machine, in particular to an automatic paging machine which can accurately supply bags to an automatic bagging machine. Background Art

[0002] The paging machine is also called a sorting machine. It is used to automatically separate the stacked packaging bags and output them as single pages through the conveyor belt. Generally, the paging machine is used in conjunction with the bagging machine and the sealing equipment. When working, the paging machine, as the front-end equipment, conveys a single packaging bag to the bagging machine. The bagging machine puts the product into the packaging bag and then transfers it to the sealing equipment for sealing.

[0003] Existing paging machines for plastic packaging bags usually include a bag storage unit, a bag taking unit, a conveying unit, and a detection unit. The bag taking unit takes out the packaging bags from the bag storage unit one by one and puts them on the conveying unit. The conveying unit outputs a single packaging bag. When the detection unit detects a signal, it indicates that the packaging bag has reached the preset output position. At this time, the bag taking unit and the conveying unit are paused, and the bagging machine takes the packaging bag to perform bagging, sealing and other processes. This type of paging machine often has the following problems when used:

[0004] Due to inertia, when the detection unit detects the packaging bag and the conveyor belt stops, the packaging bag tends to continue to move forward for a distance, causing the packaging bag to exceed the preset output position, and the distance the packaging bag exceeds each time is often inconsistent. After connecting with the bagging machine, the above situation will cause the suction position of the bagging machine to be inconsistent when taking the packaging bag away, and then after transferring to the sealing equipment, the positioning position on the sealing equipment is also inconsistent, resulting in non-standard sealing position, sealing abnormalities, packaging bag damage and other quality problems. Utility Model Content

[0005] In order to solve the above deficiencies in the prior art, the utility model aims to provide an automatic paging machine to prevent packaging bags from exceeding a preset output position.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: an automatic paging machine, including a conveying unit, a bag storage unit fixedly arranged above the starting end of the conveying unit, a bag taking unit fixedly arranged below the starting end of the conveying unit and corresponding to the bag storage unit, a supporting pad fixedly arranged below the end of the conveying unit, and a detection unit fixedly arranged above the end of the conveying unit; the detection end of the detection unit is toward the end of the supporting pad away from the bag storage unit; a positive baffle is fixedly arranged at the end of the supporting pad away from the bag storage unit, and the positive baffle extends vertically upward to the top of the conveying unit.

[0007] As a limitation of the present invention, at least two positive baffles are arranged at equal intervals along the width direction of the conveying unit.

[0008] As a further limitation of the present utility model, the upright baffle is provided with an elongated hole for adjusting the fixed height of the upright baffle.

[0009] As another limitation of the present invention, the conveying unit is an electric belt line having at least two conveying belts, and the conveying belts are O-shaped belts.

[0010] As a further limitation of the present utility model, the bag taking unit includes a linear drive assembly and a bag taking suction cup fixedly mounted on a power output end of the linear drive assembly, and the bag taking suction cup faces a discharge end of the bag storage unit.

[0011] As a further limitation of the present invention, the supporting pad is a polytetrafluoroethylene plate.

[0012] As a further limitation of the present invention, the detection unit is a fiber optic electric eye.

[0013] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0014] (1) The utility model has a positive baffle fixed on the end of the support pad away from the bag storage unit. When the packaging bag is transferred to the end of the support pad through the O-belt, the positive baffle can block the packaging bag to prevent it from moving backwards, thereby preventing the packaging bag from exceeding the preset output position. The single-page packaging bag is accurately positioned when it is output, so that the packaging bag on the bagging machine and sealing equipment can be accurately positioned, thereby avoiding the situation of inadequate packaging and abnormal sealing.

[0015] (2) The support pad provided in the utility model can provide support for the packaging bag (soft bag), making it convenient for the bagging machine to press down and grab the packaging bag on the conveying unit.

[0016] (3) The conveying unit in the utility model is at least two O-shaped belts arranged at intervals. The bag taking suction cup in the bag taking unit can move up and down in the gap of the O-shaped belt. After the upper action position absorbs the packaging bag in the bag storage unit (that is, after completing the bag taking action), it moves down to the lower action position to unload the packaging bag onto the O-shaped belt to achieve the paging operation. The overall action is simple and can effectively improve work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention, and are not used to limit the present invention.

[0023] This embodiment discloses an automatic paging machine, such as Figure 1 As shown, it includes a conveying unit 1, a bag storage unit 2, a bag taking unit 3, a supporting pad 4, a detection unit 5 and a positive baffle 6.

[0024] The transmission unit 1 is an electric belt line in the prior art, which includes at least two transmission belts driven by a motor. Figure 1 As shown, the conveyor belt in this embodiment is an O-shaped belt 7, and three belts are arranged at equal intervals. The bag storage unit 2 is fixed above the starting end of the conveyor unit 1 and is surrounded by three L-shaped baffles. Figure 1 As shown, two L-shaped baffles are respectively fixed vertically at the two ends of another L-shaped baffle, and the shorter side of the L-shaped baffle forms a support edge for placing the packaging bag. The bag taking unit 3 is fixed below the starting end of the conveying unit 1, corresponding to the above-mentioned bag storage unit 2, as shown in FIG. Figure 1 and Figure 2 As shown, the bag taking unit 3 includes a bag taking suction cup 31 and a linear drive assembly 32. In this embodiment, the linear drive assembly 32 is a cylinder, and two bag taking suction cups 31 are fixedly provided on the power output end of the linear drive assembly 32, and the two bag taking suction cups 31 are both facing the bottom of the bag storage unit. When in motion, the bag taking suction cup 31 can be driven by the linear drive assembly 32 to move up and down in the vertical direction.

[0025] The support pad 4 is fixedly arranged below the end of the conveying unit 1, which is the output position of the packaging bag preset in this embodiment. Specifically, the support pad 4 is made of PTFE plate, and both ends are fixed to the frame of the conveying unit 1 by bolts, slightly lower than the upper half of the O-shaped belt 7 in the conveying unit 1.

[0026] The detection unit 5 is also fixed at the end of the conveying unit 1, located above. In this embodiment, the detection unit 5 is a fiber optic electric eye fixed to one side of the frame of the conveying unit 1 through a bracket, and the fiber optic electric eye faces the end of the support pad 4 away from the bag storage unit 2. When working, the fiber optic electric eye can detect whether the packaging bag is transported to the preset packaging bag output position (i.e., above the support pad 4).

[0027] The positive baffle 6 is mounted on the end of the support pad 4 away from the bag storage unit 2, and is vertically arranged, and the top end extends to the top of the O-shaped belt 7. In this embodiment, three positive baffles 6 are arranged at equal intervals, each of which is a stainless steel plate with a length of 6 cm and a width of 3 cm, and a long strip hole is opened at the center of the stainless steel plate. Figure 1 As shown, the alignment baffle 6 is fixed on the end surface of the support pad 4 through a long hole and an external hexagonal bolt, and the fixed height of the alignment baffle 6 can be adjusted through the long hole during installation to make it more suitable for the thickness of the packaging bag currently paging.

[0028] The working process of this embodiment is as follows: the packaging bags are stacked into the bag storage unit 2, and the bag picking suction cup 31 in the bag picking unit 3 moves upward under the control of the linear drive component 32, and after sucking a single packaging bag, it moves downward under the control of the linear drive component 32. When it reaches the upper surface position of the O-shaped belt 7, the bag picking suction cup 31 releases the packaging bag, and the packaging bag is transmitted to the end along with the O-shaped belt 7. When it reaches above the supporting pad 4, the positive baffle 6 blocks the packaging bag to prevent it from continuing to be transmitted backward. At the same time, the detection unit 5 detects that the packaging bag is at the preset output position and transmits a signal to the controller. The controller controls the O-shaped belt 7 to stop running, and then the material picking robot arm of the bagging machine grabs the packaging bag for loading. When the material picking robot arm grabs the packaging bag, since the packaging bag is a soft bag, the supporting pad 4 located under the packaging bag supports the packaging bag, which is convenient for the robot arm to grab.
