Description

Technical Field

[0001] This invention relates to the field of continuous production equipment for bagged packaging materials, and in particular to a continuous bag-packing adhesive tape device and continuous bag-packing production equipment. Background Technology

[0002] Continuous bag packaging, consisting of multiple bags linked together, is widely used in the packaging of food, processed foods, condiments, and pharmaceuticals. In continuous bag packaging, adjacent bags are separated by heat sealing. Due to limitations in the manufacturing process, material jamming and leakage are unavoidable during production. Once these issues occur, the defective bags must be removed to prevent food safety problems such as mold growth on the packaged goods during subsequent use.

[0003] During the production process, when an abnormal bag is encountered and removed, the original continuous bags will be broken. In subsequent use, the continuous bags must be used in a string (belt) or in a reel with the subsequent equipment. Therefore, after the abnormal bag is removed, the broken continuous bags must be reconnected. In other words, the bags on both sides of the break formed at the location where the abnormal bag was removed must be reconnected. The connection of continuous bags is mainly done by using adhesive tape.

[0004] Currently, the application of tape at the break point during continuous bag production is all done manually. That is, when there is a break, the tape is temporarily cut from the tape roll and stuck to the break point of the continuous bag. This method is not only inefficient, but also makes it difficult to guarantee the bonding quality. In severe cases, the continuous bag may even break unexpectedly during later use. Summary of the Invention

[0005] The purpose of this invention is to provide a continuous bag packaging tape application device to solve the problems of low tape application efficiency and difficulty in ensuring bonding quality in the existing continuous bag packaging production process.

[0006] Meanwhile, the present invention also aims to provide a continuous bag production equipment using the above-mentioned continuous bag adhesive tape device to solve the above-mentioned problems.

[0007] To solve the above problems, the continuous bag-packing adhesive tape device of the present invention adopts the following technical solution: the continuous bag-packing adhesive tape device includes a bag clamping device, the bag clamping device includes a first claw and a second claw, a clamping opening for continuous bags to enter is provided between the first claw and the second claw, and an adhesive tape holding device is provided at the end of the clamping opening, the adhesive tape holding device includes an adhesive tape holding arm for temporarily holding the back of the adhesive tape, the adhesive tape holding arm is provided on the corresponding claw, or the adhesive tape holding arm is fixed relative to the bag clamping device and has a clearance opening corresponding to the clamping opening for continuous bags to enter.

[0008] Beneficial Effects: The technical solution of the continuous bag-packing tape-applying device of the present invention is a pioneering invention. Specifically, the continuous bag-packing tape-applying device of the present invention, by setting a clamping opening between the first and second claws of its bag-clamping device, can complete the clamping action when the bag enters the clamping opening. At the same time, since a tape holding arm is set at the clamping opening, the tape to be used can be held on the tape holding arm in advance during use. When the continuous bag enters the clamping opening, the tape is pressed into the clamping opening, thereby completing the tape-applying action when the bag-clamping device clamps. Since the tape is pushed into the clamping opening by the bag (while the tape is in contact with the bag), a good fit between the bag and the tape is ensured. The first and second claws achieve tightness of the tape, ensuring the flatness, consistency, and tightness of the tape application, thereby ensuring the quality of the tape application. In summary, the continuous bag-packing tape-applying device of the present invention solves the problems of low tape-applying efficiency and difficulty in ensuring bonding quality in the existing continuous bag production process.

[0009] Furthermore, the tape holding arm is a tape adsorption arm for adsorbing the back side of the tape, and the tape adsorption arm is provided with a negative pressure suction port. The adsorption arm has the advantages of simple structure and ease of implementation. Compared with electrostatic adsorption and other methods, the negative pressure suction port has the advantages of simple structure and reliable adsorption.

[0010] Furthermore, the negative pressure suction ports are arranged in at least two rows along the width of the corresponding tape adsorption arm. This arrangement of at least two rows of negative pressure suction ports will further enhance the reliability of adsorption.

[0011] Furthermore, the bag clamping device is equipped with a base, and a feeding device is provided between the base and the bag clamping device to drive the bag clamping device to move so that continuous bags enter its clamping opening. The configuration of the feeding device can automate the operation of the adhesive tape device when necessary.

[0012] Furthermore, the bag clamping device is guided to the base, and the feeding device includes a drag belt rotatably wound around the base, the drag belt being fixedly connected to the bag clamping device. The drag belt has the advantages of simple structure and ease of arrangement and control.

[0013] Furthermore, the base is equipped with a support frame, and the base is rotatably mounted on the support frame, having both a horizontal and a vertical position. When in the vertical position, the holding side of the tape holding arm faces downwards. The vertical position facilitates cooperation with a corresponding tape supply device, enabling the tape-adhesive device to automatically pick up the tape.

[0014] Furthermore, the base is mounted to the support frame via a pivot, which engages with the base to prevent rotation. A pitch drive device is connected to the pivot for transmission. Connecting the pitch drive device via a pivot has the advantage of simple structure and makes it easier to modularize the various parts.

[0015] Furthermore, a friction-reducing rolling element is provided at the transition position between the tape holding arm and the corresponding gripper. The friction-reducing rolling element can reduce the frictional force when the back of the tape slides relative to the tape holding arm, facilitating the smooth insertion of the tape into the clamp.

[0016] Furthermore, the friction-reducing rolling element is a friction-reducing roller. Using a friction-reducing roller as the friction-reducing rolling element has the advantages of simple structure and easy assembly.

[0017] The continuous bag production equipment of the present invention adopts the following technical solution: continuous bag production equipment, the equipment includes a continuous bag adhesive tape device, the continuous bag adhesive tape device includes a bag clamping device, the bag clamping device includes a first claw and a second claw, a clamping opening for continuous bags to enter is provided between the first claw and the second claw, and an adhesive tape holding device is provided at the end of the clamping opening, the adhesive tape holding device includes an adhesive tape holding arm for temporarily holding the back of the adhesive tape, the adhesive tape holding arm is provided on the corresponding claw, or the adhesive tape holding arm is fixed relative to the bag clamping device and has a clearance opening corresponding to the clamping opening for continuous bags to enter.

Specifically, the continuous bag tape application device has a clamping opening between the first and second claws of its bag clamping device, which can complete the clamping action when the bag enters the clamping opening. Simultaneously, because a tape holding arm is provided at the clamping opening, the tape to be used can be held on the tape holding arm beforehand. When the continuous bag enters the clamping opening, the tape is pressed into the clamping opening, thus completing the tape application action when the bag clamping device clamps. Since the tape is pushed into the clamping opening by the bag (while the tape is in contact with the bag), good adhesion between the bag and the tape is ensured. The first and second claws achieve tight adhesion of the tape, ensuring the flatness, consistency, and tightness of the tape application, thereby guaranteeing the quality of the tape application. In summary, the continuous bag tape application device of the present invention solves the problems of low tape application efficiency and difficulty in guaranteeing adhesion quality in the existing continuous bag production process.

Detailed Implementation

[0030] During the production of continuous bags 1001, some bags may experience material jamming or leakage. Once this occurs, these defective bags need to be removed to meet food safety and other relevant requirements. After the defective bags are removed, a break is created in the original continuous bag 1001, disrupting its continuity. To maintain the continuity of the continuous bag 1001, adhesive tape is used to bond the bags together at the break. The continuous bag adhesive tape device of this invention is used to bond the continuous bags at the break. The basic inventive concept of this continuous bag adhesive tape device is to provide a bag clamping device that can clamp the bags at the point where they need to be joined, and to provide a tape adsorption arm at the clamping inlet of the bag clamping device to adsorb the adhesive tape needed for bonding. When bonding bags, as the bags enter the clamping opening, the tape on the tape adsorption arm is pushed into the clamping opening of the bag clamping device, and is then glued to the connection point of the two bags as the bag clamping device clamps them.

[0031] Figure 1 The figure illustrates the usage of an embodiment of the continuous bag-pack adhesive tape device of the present invention. As shown, the continuous bag-pack adhesive tape device is arranged on one side of the conveying path of the continuous bags 1001 during use. When there are abnormal bags, and after the abnormal bags are rejected, the bags on both sides of the break can be aligned, and then the aligned bags can be bonded together by the continuous bag-pack adhesive tape device of the present invention.

[0032] The structure of the adhesive tape device 102 is as follows Figure 2As shown, the system includes a support frame 201 and a rotatable base mounted on the support frame 201, specifically a rotatable base plate 209. A synchronous pulley 202 and a synchronous belt 203 are mounted on the support frame 201. A rotatable pulley 225 is mounted on the rotatable base plate 209, and the pulley 225 is fixed to the rotatable base plate 209, with its axle forming the rotatable shaft 204 of the rotatable base plate 209. In use, the rotatable base plate 209 can be rotated by the synchronous belt 203, allowing it to be in a vertical position for picking up tape and a horizontal position for sticking tape. A first sensor 205 is mounted on the top of the support frame 201 to define the horizontal rotation position of the rotatable base plate 209. The first sensor 205 is equipped with a rotation upper signal plate 206. A fourth sensor 224 is mounted on one side of the support frame 201 to define the vertical rotation position of the rotatable base plate 209. The fourth sensor 224 is equipped with a rotation lower signal plate 221.

[0033] A linear guide rail 215 for adhesive tape is installed on the flip-over base plate 209, and a bag clamping device is mounted on the linear guide rail 215. The bag clamping device includes adhesive tape grippers 214, with two grippers, namely a first gripper and a second gripper, forming a clamping opening between the first and second grippers. The adhesive tape grippers 214 are used to clamp the bags that enter their clamping opening. Specifically, the adhesive tape grippers 214 can be pneumatic grippers, etc., and are equipped with adhesive tape suction arms. Figure 2 In the illustrated embodiment, the tape adsorption arm is a tape adsorption plate 216 located at the end of the tape gripper 214. The tape adsorption plate 216 is a negative pressure suction plate, and the negative pressure suction plate is provided with suction holes for adsorbing the back of the tape. Figure 2 In the illustrated embodiment, two rows of suction holes are arranged along the width of the negative pressure suction plate. Of course, based on the fundamental function of the suction holes in adsorbing the back of the tape, in some embodiments, the suction holes may be arranged in only one row, or even three or more rows; this should be understood by those skilled in the art. Furthermore, to reduce the frictional force when the tape moves relative to the tape adsorption arm, friction-reducing rolling elements are provided at the transition point between the tape adsorption arm and the gripper. Figure 2 In the illustrated embodiment, the friction-reducing rolling element specifically uses a friction-reducing roller. In other embodiments, the friction-reducing rolling element may also be a ball, a roller, etc.

[0034] In the above embodiments, the tape adsorption arm actually forms a tape holding arm. In order to hold the tape, in addition to the tape adsorption arm mentioned above, the tape holding arm can also adopt a flat plate structure, and an electric pressure plate or pneumatic gripper is provided on the flat plate to temporarily fix the tape.

[0035] Although Figure 2In the illustrated embodiment, the tape suction arm is located at one end of the gripper near the clamping end and forms an outward-facing structure perpendicular to the gripper. However, in some cases, the tape suction arm can be configured to be fixed relative to the fixed part of the bag clamping device and movable relative to the gripper. In this case, for example, when the bag clamping device uses a pneumatic gripper, the tape suction arm can be fixed to the cylinder of the pneumatic gripper, as long as the tape suction arm has an allowance opening at the clamping end of the bag clamping device for the tape to be pushed into the clamping end.

[0036] exist Figure 2 In the illustrated embodiment, the installation structure of the tape gripper 214 is as follows: a push motor mounting bracket 210 is provided on the flip base plate 209, and a tape push motor 207 is mounted through the push motor mounting bracket 210. The tape push motor 207 is driven by a belt mechanism, which includes a belt idler pulley 217 and a belt 218 mounted on the flip base plate 209 via a belt idler pulley axle 219. The belt idler pulley axle 219 cooperates with a belt idler pulley mounting plate 220 provided on the flip base plate 209. A gripper connecting plate 213 is mounted on the tape adhesive linear guide 215, and the gripper connecting plate 213 is connected to the belt through a belt connecting plate 212. The tape gripper 214 is connected to the gripper connecting plate 213 and can reciprocate along the tape-adhesive linear guide 215 driven by the belt 218, thereby switching between its tape-adhesive position and its position to avoid the continuous bags 1001. Thus, the belt effectively acts as a drag belt, pulling the gripper connecting plate back and forth during the reciprocating movement. To accurately control the stopping position of the tape gripper 214, a tape-pushing mechanism signal plate 211, a second sensor 208, and a third sensor 223 are installed on the flip base plate 209. The third sensor 223 is mounted on the flip base via a sensor fixing plate 222.

[0037] The working principle of the continuous bag adhesive tape device of the present invention is as follows: After the bags are aligned at both sides of the break in the continuous bag, the tape gripper 214 is driven to approach the aligned bag position by the feeding mechanism consisting of the tape push motor 207 and the belt 218. At this time, transparent tape is adsorbed on the tape adsorption arm. When the front end of the gripping jaw of the tape gripper 214 meets the side of the bag, the bag enters the gripping jaw of the tape gripper, and the tape on the tape adsorption arm is pushed into the tape gripping jaw. At the same time, it is folded on both sides of the aligned bag position. At this time, the tape gripper 214 clamps and the bag is bonded. After one bonding process is completed, the tape adsorption arm can be moved to the tape picking position by flipping the base plate 209 backward, rotating, or tilting it down. At this time, in conjunction with the corresponding tape supply belt and other devices, the function of automatically adding tape can be realized.

[0038] exist Figure 2In the illustrated embodiment, the bag clamping device is equipped with a support frame and is configured to have two positional orientations. In some embodiments, when the tape is supplied perpendicular to the horizontal plane, the support frame can be omitted, and the base of the bag clamping device can be fixed in a corresponding position. Additionally, besides using... Figure 2 In addition to the structure with a feeding mechanism such as a drag belt, the adhesive tape device can also be designed as a handheld structure. Even with a handheld, manually operated structure, it still offers significant advantages in terms of adhesion efficiency and quality compared to manual tape application in existing technologies. Of course, the feeding mechanism can also be a push-pull hydraulic cylinder, pneumatic cylinder, gear rack, screw and nut mechanism, etc. When using a push-pull hydraulic cylinder or pneumatic cylinder, one end is connected to the base, and the other end is connected to the bag clamping device. When using a screw and nut mechanism, the screw is mounted on the base, and the nut is mounted on the bag clamping device.
