Description

TECHNICAL FIELD

[0001] The utility model relates to the field of packing machinery especially relates to a double-sided hand-loop bag handle pasting mechanism of bag body. BACKGROUND

[0002] In the modern packaging industry, the paper bag with hand-loop bag handle is usually formed by the method of pasting hand-loop bag handle first and then folding the bag body into a cylinder, that is, the hand-loop bag handle is pasted on the surface of the sheet material when the sheet material is output, and then the whole bag is made through the processes of folding into a cylinder, edge sealing, cutting, bottom forming and the like. This process has the following significant defects: the thickness of the bag opening area is uneven after pasting the hand-loop bag handle, since the hand-loop bag handle has been pasted on the sheet material, in the subsequent folding process, the bag opening part is obviously thickened due to the superposition of the glue layer and the hand-loop material, and the hand-loop rope body extends outward, which causes the hand-loop bag handle to easily interfere with the equipment components during the conveying process, such as being scraped and pulled by the clamping mechanism, resulting in the hand-loop falling off or the bag body deviating, especially the sheet material with the pasted bag handle in the cylinder forming and bottom folding steps affects the bag body yield and the equipment running stability.

[0003] Therefore, there is an urgent need for a new bag handle pasting mechanism that can overcome the above-mentioned defects and accurately paste the hand-loop bag handle on both sides after the bag body is formed, thereby improving the product quality and production efficiency. UTILITY MODEL CONTENT

[0004] The utility model provides a double-sided hand-loop bag handle pasting mechanism of bag body aiming at the defects in the prior art.

[0005] The utility model solves the above-mentioned technical problems through the following technical scheme:

[0006] The double-sided hand handle bag body pasting mechanism comprises a mounting frame, a bag body conveying turntable, a limiting piece, and a handle pasting device. The bag body conveying turntable is mounted on the mounting frame. The bag body conveying turntable is circumferentially provided with a first handle pasting station and a second handle pasting station. When the bag body is located at the first handle pasting station and the second handle pasting station, the bag opening extends out of the bag body conveying turntable and is turned by at least 90°. The limiting piece is circumferentially arranged along the outer surface of the bag body conveying turntable. The limiting piece contacts the outer surface of the bag body to keep the bag body pressed on the outer surface of the bag body conveying turntable. The bag body conveying turntable rotates under the driving of a rotating power source or / and the limiting piece drives the bag body to move, so that the bag body is conveyed along the bag body conveying turntable in a clockwise or counterclockwise direction. At least two groups of handle pasting devices correspond to the bag opening positions of the bag body at the first handle pasting station and the second handle pasting station. The handle pasting device comprises a material supporting component on both sides of the bag opening and a handle pasting component. The handle pasting device further comprises a handle conveying device for conveying the hand handle to the handle pasting component. The handle pasting component moves and presses a single hand handle on the bag opening on the material supporting component. The handle pasting step is placed after the bag body is basically formed, which completely avoids the uneven thickness of the bag opening caused by early handle pasting in the traditional process. The bag body is turned by more than 90° on the conveying turntable, so that the handles are pasted on the two sides of the bag body respectively. Compared with bag body turning, the double-sided handle pasting can save floor area and facilitate double-sided handle pasting. Two groups of independent handle pasting devices act on two stations respectively, so that double-sided handle pasting can be completed in the same turntable cycle, which greatly improves the efficiency. The limiting piece cooperates with the bag body conveying turntable to convey the bag opening in a suspended state. However, the main position of the bag body at the bottom is pasted on the bag body conveying turntable. The bag body can stably enter the first handle pasting station and the second handle pasting station in sequence for handle pasting without the influence of other mechanisms. After handle pasting, the bag body is formed, and the hand handle does not affect the subsequent processes.

[0007] Preferably, the limiting piece comprises a plurality of conveying rollers circumferentially arranged along the bag body conveying turntable. The conveying rollers are mounted on the mounting frame and can be actively or passively rotated. The conveying rollers or the bag body conveying turntable drive the bag body conveying or the conveying rollers and the bag body conveying turntable rotate towards each other to drive the bag body to convey forward through friction with the surface of the bag body.

[0008] Preferably, the limiting piece comprises a conveying belt on the surface of the bag body conveying turntable. The conveying belt contacts the inner surface of the bag body and drives the bag body to convey along the bag body conveying turntable in a clockwise or counterclockwise direction through rotation. The conveying belt can be pressed on the surface of the bag body conveying turntable to adapt to the curvature of the bag body conveying turntable, so that the bag body can be pressed on the surface of the bag body conveying turntable. The conveying belt or the bag body conveying turntable drives the bag body conveying through friction with the surface of the bag body, or the bag body conveying turntable rotates the conveying belt, and the two convey the bag body in the conveying direction.

[0009] As preferred, the handle attaching component is connected with a negative pressure source. When the handle attaching component obtains the hand-holding bag handle at the output position of the bag handle conveying device, the hand-holding bag handle can be moved to the bag opening handle attaching position by negative pressure suction, and the handle attaching component can be quickly released by discontinuing the negative pressure at the placement moment.

[0010] As preferred, the handle attaching device comprises a bag handle transfer turntable, and a plurality of handle attaching components are uniformly arranged on the circumference of the bag handle transfer turntable. The outer side surface of the handle attaching component has the same curvature as the outer circumferential surface of the bag handle transfer turntable, and the outer side surface of the handle attaching component is further provided with an air hole connected with the negative pressure source. The bag handle transfer turntable rotates and drives the handle attaching component to reciprocate between the output position of the bag handle conveying device and the handle attaching position of the first handle attaching station or the second handle attaching station. The handle attaching device is block-shaped and is attached to the surface of the bag handle transfer turntable, and the handle attaching device protrudes from the outer arc surface of the bag handle transfer turntable. Alternatively, the handle attaching device is block-shaped and is embedded in the mounting groove matched with the bag handle transfer turntable, so that the handle attaching device and the outer surface of the bag handle transfer turntable cooperatively form a complete circular arc surface or an almost flush arc surface close to the circular arc surface. The rotation of the bag handle transfer turntable can make one side of the handle attaching device obtain the hand-holding bag handle at the bag handle conveying device, and the other side of the handle attaching device attach the hand-holding bag handle to the bag opening in cooperation with the material supporting component. If there are more than two stations, the handle attaching device is in the transfer conveying state while the above-mentioned two sides are in action. The efficiency of handle attaching is greatly increased, and the conveyed bag body can be attached without waiting, thereby increasing the speed of equipment operation.

[0011] As preferred, the handle attaching device further comprises a hand-holding bag handle material roller and a cutting device. The hand-holding bag handle material roller and the cutting device are connected with the conveying device. The hand-holding bag handle material roller continuously conveys the hand-holding bag handle to the cutting device, and the cutting device continues to convey the single hand-holding bag handle to the handle attaching component through the bag handle conveying device after cutting. The cutting device accurately cuts according to the set length, and the hand-holding bag handle is conveniently supplied from the roll material to the single piece.

[0012] As preferred, the outer side surface of the handle attaching component is provided with a groove for accommodating the hand-holding rope, and the extension direction of the groove is parallel to the central rotating shaft of the bag handle transfer turntable. The hand-holding rope body is fixed by limiting during the adsorption and transportation process, and is positioned by the hand-holding rope body, so as to ensure the accuracy of handle attaching. Meanwhile, the accommodation of the hand-holding rope body in the groove can make the hand-holding sheet material adsorbed on the surface of the handle attaching component, so as to avoid the unevenness of the hand-holding on the surface of the handle attaching component and make the conveying more stable.

[0026] A double-sided hand-hold bag handle pasting mechanism of a bag body, as shown in Figures 1-3 the drawings, comprises a mounting frame 1, a bag body conveying turntable 2, a limiting member 3, and a handle pasting device 4. The bag body conveying turntable 2 is mounted on the mounting frame 1, and the bag body conveying turntable 2 is provided with a first handle pasting station and a second handle pasting station in the circumferential direction. When the bag body is located at the first handle pasting station and the second handle pasting station, the bag opening extends out of the bag body conveying turntable 2 and is oriented to be turned by at least 90°. The limiting member 3 is arranged in the circumferential direction along the outer surface of the bag body conveying turntable 2. The limiting member 3 contacts the outer side surface of the bag body to keep the bag body pressed against the outer surface of the bag body conveying turntable 2. The bag body conveying turntable 2 is driven to rotate by a rotating power source 21 or / and the limiting member 3 drives the bag body to move, so that the bag body is conveyed along the bag body conveying turntable 2 in the clockwise or counterclockwise direction. At least two groups of handle pasting devices 4 correspond to the bag opening positions of the bag body at the first handle pasting station and the second handle pasting station, respectively. The handle pasting device 4 comprises a material supporting part 41 located on both sides of the bag opening and a handle pasting part 42. The handle pasting device 4 further comprises a handle conveying device 43 for conveying the hand-hold bag handle to the handle pasting part 42. The handle pasting part 42 moves and presses a single hand-hold bag at the bag opening of the bag body on the material supporting part 41.

[0027] The limiting member 3 comprises a plurality of conveying rollers arranged in the circumferential direction along the bag body conveying turntable 2. The conveying rollers are mounted on the mounting frame 1 and can be driven to rotate actively or passively.

[0028] As shown in Figure 4 the drawings, the limiting member 3 comprises a conveying belt 31 on the surface of the bag body conveying turntable 2. The conveying belt 31 contacts the inner side surface of the bag body and drives the bag body to be conveyed along the bag body conveying turntable 2 in the clockwise or counterclockwise direction by rotating.

[0029] The handle pasting part 42 can be connected with a mechanical hand to move back and forth to obtain the hand-hold bag handle by suction or clamping and then paste the hand-hold bag handle at the bag opening position. Alternatively, the handle pasting part 42 can press the hand-hold bag handle conveyed by the handle conveying device 43 downward at the bag opening position. As one of the embodiments, the handle pasting part 42 is connected with a negative pressure source, and the handle pasting part 42 is a suction disc or a plate with suction holes.

[0030] As shown in Figure 5 one of the embodiments in which the handle pasting part 42 is connected with a negative pressure source, the handle pasting device 4 comprises a handle conveying turntable 44. The handle conveying turntable 44 is uniformly provided with a plurality of handle pasting parts 42 in the circumferential direction. The outer side surface of the handle pasting part 42 has the same curvature as the outer circumferential surface of the handle conveying turntable 44. The outer side surface of the handle pasting part 42 is further provided with air holes connected with the negative pressure source. The handle conveying turntable 44 rotates and drives the handle pasting part 42 to move back and forth between the output position of the handle conveying device 43 and the handle pasting position of the first handle pasting station or the second handle pasting station.

[0031] The bag attaching device 4 also includes a bag handle material roller 45 and a cutting device 46. The bag handle material roller 45 and the cutting device 46 are connected to the conveyor. The bag handle material roller 45 continuously conveys the bag handle and sends it to the cutting device 46. After cutting, the cutting device 46 continues to convey the single bag handle to the bag attaching component 42 through the bag handle conveying device 43.

[0032] The outer surface of the handle part 42 is provided with a groove 421 for accommodating the handle rope, and the groove 421 extends in a direction parallel to the central axis of the bag handle rotating disc 44.

[0033] The sticking parts 42 of the two sticking devices 4 are located above or diagonally above the material support part 41, and the sticking is applied to the upper surface of the bag body at the first sticking station and the second sticking station.

[0034] like Figure 3 As shown, the mounting frame 1 is vertically arranged so that the central axis of the bag conveying turntable 2 is perpendicular to the vertical plane. There is an inlet 22 for the bag to enter and an outlet 23 for the bag to exit between the bag conveying turntable 2 and the limiting member 3.

[0035] It also includes a hopper 5 for stacking bags, which is mounted on the mounting frame 1 and located at the corresponding inlet 22.

[0036] Working principle: The mounting frame 1 is a vertical structure, and the bag conveying turntable 2 is vertically installed in front of it, with its central axis parallel to the horizontal plane. The outer periphery of the turntable is fitted with limiting parts 3, so that the bag is accommodated between the two.

[0037] like Figure 1 As shown, the hopper 5 is installed on one side of the mounting frame. The bags in the hopper 5 have an inlet 22 between the bag conveying turntable 2 and the limiting member 3 for the bags to enter. As an alternative implementation, bags formed by the bag forming equipment can also be directly fed into the inlet 22 between the bag conveying turntable 2 and the limiting member 3 via an online connection, or individual bags can be manually placed into the inlet 22. Regardless of the implementation, the bags entering the inlet 22 are conveyed in the conveying direction under the combined action of the bag conveying turntable 2, the limiting member 3, or both, sequentially delivering the bags to the first and second attaching stations. Referring to the attached drawings, the conveying direction in this embodiment is clockwise.

[0038] Bag conveying scheme 1: Several conveying rollers are arranged around the outer perimeter of the turntable. Some of them are active rollers, driven by independent motors, and are slightly pressed against the outer surface of the bag. They assist the turntable in driving the bag to be conveyed clockwise or counterclockwise.

[0039] The second bag conveying scheme is to use a closed conveying belt 31, part of the surface of which is attached to the arc surface of the outer periphery of the rotating disc, and contacts the surface of the bag body. The bag body is driven by the belt movement or the auxiliary rotating disc to move clockwise or counterclockwise.

[0040] The working process of the handle attaching device

[0041] The handle bag material roller 45 is used to place the rolled handle paper material or the handle bag with the handle rope attached. If the rolled handle paper material is placed, the handle bag material roller 45 and the cutting device 46 are connected by a device for sending the rope to attach the rope to the handle paper. This device is a conventional structure in the field, and will not be described here. Regardless of the way, the handle bag with the rope attached is a continuous handle bag when it passes through the cutting device 46. The cutting device 46 intermittently or according to the control instruction cuts the continuous handle bag into a fixed length. The cutting device can be a cutting knife provided on a knife roller, which cuts the handle bag once by rotating or lifting. The cutting device can also be a circular knife with knife edges arranged in the circumferential direction. The cutting device can also be a cutting knife provided on a guide rail, which cuts the handle bag by reciprocating motion. Since the bag opening is directed outward of the bag conveying rotating disc 2, the handle rope on the handle paper is also directed outward of the bag conveying rotating disc 2 in the opposite direction of the bag body.

[0042] The bag handle conveying device 43 can include one or more conveying rollers, guide plates, and suction cups connected to negative pressure. The single handle bag output by the cutting device 46 is conveyed to the handle attaching component 42 by various conventional conveying methods driven by friction, pushing, gravity, etc. The handle attaching component 42 can directly and intermittently press the handle bag to the bag opening, or the handle attaching component 42 is connected to a movable transmission member, which can move the handle bag to the bag opening by clamping or suction. As one of the embodiments,

[0043] The handle attaching component 42 is arranged on the bag handle transfer rotating disc 44. The bag handle transfer rotating disc 44 rotates to uniformly distribute the handle attaching components 42 in the circumferential direction. For a certain handle attaching component 42, when it is transferred to the material taking position, the negative pressure is turned on to suction the single handle bag.

[0044] The transfer turntable 44 rotates to a handle attaching position matched with the material supporting part 41, the bag opening is just located between the material supporting part 41 and the handle attaching part 42, the handle attaching part 42 continues to move downward or the transfer turntable 44 rotates a small angle to complete the handle attaching, and meanwhile or before the handle attaching part 42 releases the negative pressure; the bag body passes through the first handle attaching station and the second handle attaching station in sequence, the handle attaching parts 42 corresponding to the first handle attaching station and the second handle attaching station attach the handles to the two sides of the bag opening of the bag body respectively. The bag body is turned over on the surface of the bag body conveying turntable 2, since the bag opening is turned at least by 90 degrees, preferably, the handle attaching parts 42 of the two groups of handle attaching devices 4 are located above or obliquely above the material supporting part 41, and the handles are obliquely above or above the bag body when the handle attaching devices 4 attach the handles to the bag body, so that the handles are conveniently attached to the surface of the bag opening of the bag body. Finally, the bag body passes through the two stations and is then sent out from the bag body discharging outlet 23 and separated from the bag body conveying turntable 2, and is sent into a subsequent collecting or packaging process. The rotation of the bag handle transfer turntable 44 can make the handle attaching device 4 on one side obtain the hand-held bag handle at the bag handle conveying device 43, and the handle attaching device 4 on the other side attach the hand-held bag handle to the bag opening in cooperation with the material supporting part 41, and if there are more than two stations, the handle attaching device 4 is in the transfer conveying state at the same time as the above-mentioned two sides.

[0045] The control system coordinates the rotation of the bag body conveying turntable 2, the rotation start and stop of the transfer turntable 44, the cutting timing, the negative pressure on-off and the like, and ensures that each station is strictly synchronized.
