Description

Technical Field

[0001] This utility model relates to automatic bag feeding equipment, specifically to an automatic bag feeding device for packaging bags that can prevent the bag pusher and bag holder from hitting the folding machine. Background Technology

[0002] The most important components of an automatic bag-feeding device for packaging bags are the bag-pushing and supporting rod 01 and the folding machine 02. In existing technology, their structures are typically as follows: Figure 1 As shown, the bag-pushing and supporting rod 01 includes two supporting components, which are symmetrically arranged on both sides of the folding machine 02. Each supporting component includes a supporting rod 011 and a pushing mechanism 012 connected to the supporting rod 011. The supporting rod 011 is C-shaped, and the openings of the two supporting rods 011 are opposite to each other. After the material inside the packaging bag is filled, the bag clamp responsible for fixing the packaging bag is released, and the packaging bag falls into the pushing and supporting rod 01, straightening the opening of the packaging bag. Then, under the action of the pushing mechanism 012, the packaging bag is pushed towards the folding machine 02. Figure 2 As shown, the folding machine 02 includes a frame 021 and two sets of folding components 022 mounted on the frame 021. The two sets of folding components 022 are located on the side of the frame 021 near the pusher and bag-supporting rod 01, and are arranged vertically. Each set of folding components 022 has a gap in the middle for the bag opening to pass through. When the pusher and bag-supporting rod 01 feeds the bag into the folding machine 02, the lower folding component 022 is exactly in the opening of the C-shaped bag-supporting rod 011, so the two parts will not interfere with each other. When the pusher and bag-supporting rod 01 feeds the bag opening into the opening of the two sets of folding components 022, the two sets of folding components 022 fold and sew the bag opening.

[0003] After the bag-pushing and bag-holding rod 01 holds the packaging bag, it is pushed into the folding machine 02 for folding and sewing. This horizontal pushing motion requires the bag-pushing and bag-holding rod 01 and the folding machine 02 to be consistent in height. If the equipment becomes loose during operation, causing a large change in the height of either of them, a collision will occur, which may even damage the equipment in severe cases. Utility Model Content

[0004] The purpose of this invention is to solve the technical problem that collisions easily occur when the height of one of the pusher and support rods of the existing automatic bag feeding equipment changes significantly during the process of pushing the packaging bag to the folding machine. The invention provides an automatic bag feeding device that can prevent the pusher and support rod from colliding with the folding machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic bag feeding device for packaging bags, designed to prevent the bag pusher and support rod from colliding with the folding machine, includes a correspondingly arranged bag pusher and support rod and a folding machine. The bag pusher and support rod comprises two support assemblies symmetrically arranged on both sides of the folding machine. Each support assembly includes a support rod and a pusher mechanism connected to the support rod. The support rod is C-shaped, and the openings of the two support rods are opposite each other. The folding machine includes a frame and two sets of folding assemblies mounted on the frame. The two sets of folding assemblies are positioned on the side of the frame closest to the bag pusher and support rod, and are arranged vertically. Each set of folding assemblies has a gap in the middle for the bag opening to pass through. The lower folding assembly is positioned within the opening of the support rod. Its special feature is that:

[0007] It also includes two sets of detection units;

[0008] Each detection unit group includes a photoelectric detection module and a reflective device corresponding to the photoelectric detection module;

[0009] The photoelectric detection modules of the two sets of detection units are symmetrically arranged on both sides of the frame of the bending machine. The photoelectric detection module includes a transmitter and a receiver, both of which are mounted on the frame of the bending machine.

[0010] The reflective devices of the two sets of detection units are symmetrically arranged on the two bag-holding rods of the bag-pushing and bag-holding rods and are respectively set for two photoelectric detection modules. They are used to reflect the light emitted by the emitting unit to the receiving unit.

[0011] The longitudinal width A of the reflective device satisfies: 0.8cm ≤ A ≤ 1.2cm;

[0012] The transmitting and receiving units are used for electrical connection with an external main control unit, and the drive control end of the bag pushing mechanism of the bag pushing arm is electrically connected to the main control unit.

[0013] Furthermore, the longitudinal width A of the reflective device is 1 cm.

[0014] Furthermore, the photoelectric detection module is a mirror-reflective photoelectric switch.

[0015] Furthermore, the reflective device is a reflector.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) The present invention provides an automatic bag feeding device for packaging bags that can prevent the bag pusher and bag support rod from hitting the folding machine. When the bag pusher and bag support rod pushes the packaging bag toward the folding machine, the emitting part continuously emits light. The light is reflected by the reflector and received by the receiving part. If the height of the two does not change during operation, the receiving part will continuously receive stable light. If the height changes significantly, the receiving part will not receive light. At this time, the external main control unit will control the bag pushing mechanism of the bag pusher and bag support rod to stop to prevent the collision caused by continued operation. After the height adjustment is completed, that is, the receiving part can receive stable light, the bag pusher and bag support rod will continue to run until the packaging bag is fed into the folding machine.

[0018] (2) The present invention provides an automatic bag feeding device for packaging bags that can prevent the pusher and bag support rod from hitting the folding machine. Its overall structure is simple and does not require changes to the basic structure of the existing pusher and bag support rod and folding machine. It can be used not only in newly made automatic bag feeding equipment, but also in improving the existing automatic bag feeding equipment, and has great potential for promotion.

[0019] (3) In the automatic bag feeding device for packaging bags provided by this utility model, which can prevent the pusher and bag support rod from hitting the folding machine, the longitudinal width A of the reflective device is satisfied: 0.8cm≤A≤1.2cm. This ensures that the pusher and bag support rod and the folding machine are basically consistent in height, and can prevent and reduce accidental triggering, so that the pusher mechanism of the pusher and bag support rod will stop unnecessarily.

[0020] (4) The reflective device in the automatic bag feeding device for packaging bags provided by this utility model is a reflector with a longitudinal width A of 1cm. This allows the light emitted by the emitting part to stably irradiate the reflective device within a 1cm range. The 1cm width range ensures that the pusher and the folding machine will not collide, and also reduces the difficulty of assembling and adjusting the detection unit. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and exemplary embodiments.

[0032] Reference Figures 3-6 The present invention provides an automatic bag feeding device for preventing the pusher and bag support rod from colliding with the folding machine. The device includes a pusher and bag support rod 01 and a folding machine 02. The pusher and bag support rod 01 includes two bag support components, which are symmetrically arranged on both sides of the folding machine 02. Each bag support component includes a bag support rod 011 and a pusher mechanism 012 connected to the bag support rod 011. The bag support rod 011 is C-shaped, and the openings of the two bag support rods 011 are arranged opposite to each other.

[0033] The folding machine 02 includes a frame 021 and two sets of folding components 022 mounted on the frame 021. The two sets of folding components 022 are located on the side of the frame 021 near the push bag support bar 01, and the two sets of folding components 022 are arranged vertically. Each set of folding components 022 has a gap in the middle for the bag opening to pass through. The lower folding component 022 is located inside the opening of the support bar 011.

[0034] This utility model provides an automatic bag feeding device for packaging bags that prevents the bag pusher bar from impacting the folding machine. It also includes two sets of detection units, such as... Figure 3 As shown, each detection unit includes a photoelectric detection module 1 and a reflective device corresponding to the photoelectric detection module 1, such as... Figure 5 As shown, the photoelectric detection modules 1 of the two sets of detection units are symmetrically arranged on both sides of the frame 021 of the bending machine 02. Each module includes a transmitter and a receiver, both of which are mounted on the frame 021 of the bending machine 02. The reflector 2, as shown... Figure 6As shown, the reflective devices 2 of the two sets of detection units are symmetrically arranged on the two bag-holding rods 011 of the push bag support rod 01, and are positioned relative to the photoelectric detection module 1. They are used to reflect the light emitted by the emitting unit to the receiving unit. In this way, each of the two bag-holding rods 011 will have a set of detection units to detect its height.

[0035] The photoelectric detection module 1 adopts a mirror-reflective photoelectric switch, and the reflector 2 is a reflector with a longitudinal width A satisfying: 0.8cm≤A≤1.2cm. Within this range, the light emitted by the emitting part of the photoelectric detection module 1 can be reflected by the reflector 2 to the receiving part without causing the folding machine 02 to collide with the bag pusher arm 01. In this embodiment, the longitudinal width A of the reflector 2 is 1cm, which not only ensures the detection requirements but also reduces the assembly and adjustment difficulty of the entire detection unit.

[0036] Both the transmitting and receiving units are electrically connected to the external main control unit, and the drive control end of the bag pushing mechanism 012 of the bag pushing arm 01 is electrically connected to the external main control unit. In this way, the main control unit can determine whether the height of one of them has changed significantly based on whether the photoelectric detection module 1 receives the light signal, and then control the movement of the bag pushing mechanism 012. When the height of the two changes significantly, the main control unit controls the bag pushing mechanism 012 to stop moving to prevent collision.

[0037] The method of using the automatic bag feeding device of this utility model, which can prevent the bag pusher arm from hitting the folding machine, is as follows:

[0038] S1. Place the packaging bag on the pusher bar 01, start the pusher mechanism 012 of the pusher bar 01, and the pusher bar 01 pushes the packaging bag toward the folding machine 02.

[0039] S2, The emitting part of the photoelectric detection module 1 emits light to the reflecting device 2, and the reflecting device 2 reflects the light to the receiving part;

[0040] S3. If the receiving unit receives the light reflected from the reflector 2, then proceed to step S5; if it does not receive the light, then proceed to step S4.

[0041] S4. The external main control unit controls the bag pushing mechanism 012 of the bag pushing and supporting rod 01 to stop working, adjusts the height of the bag pushing and supporting rod 01 or the folding machine 02 until the heights of the two are matched, and then controls the bag pushing mechanism 012 to continue working through the main control unit.

[0042] S5, the bag pusher bar 01 pushes the packaging bag into the folding machine 02, completing the automatic bag loading process to prevent the bag pusher bar from hitting the folding machine.

[0043] The embodiments described above are merely descriptions of specific implementations of this utility model and are not intended to limit the scope of this utility model. Various modifications and improvements made to the technical solutions of this utility model by those skilled in the art without departing from the spirit of this utility model should fall within the protection scope defined by the claims of this utility model.
