Description

Technical Field

[0001] The utility model relates to the field of paper bag making equipment, in particular to a double-head card taking and placing device for center-sealed paper bags. Background Art

[0002] In the production of center-sealed paper bags, the placement and retrieval of header cards is a crucial step. Conventional header card placement and retrieval devices are often only capable of retrieval and placement of single header cards. This makes it difficult to meet the efficient and accurate production requirements for center-sealed paper bags, where dual header cards need to be placed simultaneously. Furthermore, existing devices suffer from insufficient precision and complex operation in header card delivery and positioning, impacting production efficiency and product quality. Therefore, a device capable of retrieval and placement of single and dual header cards simultaneously is needed to improve the production efficiency and quality of center-sealed paper bags. Utility Model Content

[0003] The utility model aims at the shortcomings of the prior art and provides a double-head card taking and placing device for a center-sealed paper bag.

[0004] To solve the above technical problems, the present invention is solved by the following technical solutions:

[0005] A double-head card picking and placing device for a center-sealed paper bag includes a material bin, which includes an upper card supporting member, a lower card supporting member, an upper limit member, and a horizontal limit member. The upper card supporting member is provided with an upper supporting platform for supporting the upper head card, and the lower card supporting member is provided with a lower supporting platform for supporting the lower head card. The upper supporting platform and the lower supporting platform are parallel to each other and extend in a first direction. The upper card supporting member and the upper limit member form an upper channel for the upper head card to stand upright and be arranged along the first direction. A lower channel for the lower head card to stand upright and be arranged along the first direction is formed between the bottom of the upper card supporting member and the lower card supporting member.

[0006] It also includes a workbench for laying out the bag body, and a card-taking mechanism is provided between the hopper and the workbench. The card-taking mechanism includes a rotating shaft connected to a rotary power source, and the rotating shaft is connected to a number of suction nozzles arranged horizontally and connected to a negative pressure source. The arranged suction nozzles correspond to at least the upper head card and the lower head card position respectively. The rotating shaft rotates to drive the suction nozzles to swing, so that the suction nozzles can obtain the head card at the exit end of the upper channel and the lower channel and place the head card on the bag body on the workbench. The hopper is formed with an upper card supporting member, a lower card supporting member, an upper limit member, and a horizontal limit member to form an upper channel and a lower channel, which can store the upper head card and the lower head card respectively. The rotating shaft of the card-taking mechanism is connected to the rotary power source and the number of suction nozzles. The rotating shaft rotates to drive the suction nozzles to swing, which can obtain the head card at the exit end of the upper channel and the lower channel and place it on the bag body on the workbench, realizing the synchronous picking and placing function of dual-head cards, greatly improving production efficiency. At the same time, the head card can also be placed in the upper channel or the lower channel to realize the picking and placing of a single head card.

[0007] Preferably, the front ends of the upper card support member, the lower card support member, and the upper limit member are each provided with a limit plate. The limit plates are located at the outlet ends of the upper channel and the lower channel, respectively, and at least partially extend into the conveying path of the upper and lower header cards. This ensures the stability and accuracy of the header card discharge, prevents the header card from shifting or falling during conveyance, and improves the accuracy of header card placement and retrieval.

[0008] Preferably, the first direction extends obliquely upward, and the limiting piece is located between the surfaces on one side of the hopper to form a head card discharge surface. The angle formed between the head card discharge surface and the workbench is less than 90°, so that the angle of rotation of the rotation axis when the suction nozzle sucks and places the head card is greater than 90°. This design causes the suction nozzle to tilt the bottom surface of the head card downward when sucking the head card. Under the action of the gravity of the head card, pressure is applied to the outlet end of the upper channel or the lower channel, which is less likely to cause empty suction and facilitates the suction nozzle to better suck and place the head card.

[0009] Preferably, a nozzle mounting plate is mounted on the rotating shaft, the nozzle being mounted on the nozzle mounting plate, the nozzle mounting plate being connected to a card placement lifting power source, and the card placement lifting power source being connected to the rotating shaft. The vertical lifting of the nozzle facilitates increased interaction with the head card when removing the head card, reducing the risk of empty suction. When placing the head card, the rotating shaft rotates into position and then descends, making placement of the head card more precise.

[0010] Preferably, the nozzle mounting plate is provided with an axially extending limiting groove, in which the nozzle can be adjustably fixed, so as to facilitate adjustment of the nozzle spacing according to the size and position of the head card, further improving the adaptability of the device and the accuracy of picking and placing the head card.

[0011] The utility model has significant technical effects due to the adoption of the above technical solutions:

[0012] The double-head card picking and placing device as a whole realizes the synchronous picking and placing of single-head cards and double-head cards, improves production efficiency, ensures the accuracy and stability of head card picking and placing, and reduces production costs. At the same time, the device has strong versatility and flexibility, and can adapt to the production needs of head cards and bags of different specifications. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention is described in further detail below with reference to the accompanying drawings and embodiments.

[0019] Example 1

[0020] Double-head card picking and placing device for center-sealed paper bags, such as Figure 1-3 As shown, the material bin 141 includes an upper supporting card member 1411, a lower supporting card member 1412, an upper limit member 1413 and a horizontal limit member 1414. The upper supporting card member 1411 is provided with an upper supporting platform for supporting the upper head card, and the lower supporting card member 1412 is provided with a lower supporting platform for supporting the lower head card. The upper supporting platform and the lower supporting platform are parallel to each other, and the extension direction of the two is the first direction. The upper supporting card member 1411 and the upper limit member 1413 form an upper channel 1415 for the upper head card to stand upright and arranged along the first direction. A lower channel 1416 for the lower head card to stand upright and arranged along the first direction is formed between the bottom of the upper supporting card member 1411 and the lower supporting card member 1412.

[0021] like Figure 4 As shown, it also includes a workbench 13 for laying out the bags. A card-taking mechanism 142 is provided between the hopper 141 and the workbench 13. The card-taking mechanism 142 includes a rotating shaft 1422 connected to a rotary power source 1421. The rotating shaft 1422 is connected to a plurality of horizontally arranged suction nozzles 1423 connected to a negative pressure source. The arranged suction nozzles 1423 correspond to at least the upper and lower head card positions, respectively. The rotation of the rotating shaft 1422 drives the suction nozzles 1423 to swing, so that the suction nozzles obtain the head cards at the outlet ends of the upper channel 1415 and the lower channel 1416 and place the head cards on the bag on the workbench 13. The unique design of the hopper forms an upper channel and a lower channel through an upper card supporting member, a lower card supporting member, an upper limit member, and a horizontal limit member. The upper and lower head cards can be stored respectively, and the head cards can be arranged along the first direction. The rotating shaft of the card picking mechanism is connected to the rotary power source and several suction nozzles. The rotation of the rotating shaft drives the suction nozzles to swing, which can obtain the head card at the exit end of the upper channel and the lower channel and place it on the bag body of the workbench, realizing the synchronous picking and placing function of double-head cards, greatly improving production efficiency.

[0022] The front ends of the upper supporting member 1411, the lower supporting member 1412 and the upper limiting member 1413 are all provided with limiting plates 1424, which are respectively located at the outlet ends of the upper channel 1415 and the lower channel 1416. The limiting plates 1424 at least partially extend into the conveying path of the upper head card and the lower head card.

[0023] like Figure 2 As shown, the first direction extends obliquely upward, and the limiting piece 1424 is located between the surfaces on one side of the hopper 141 to form a head card discharge surface, and the angle formed between the head card discharge surface and the workbench 13 is less than 90°, so that the angle of rotation of the rotating shaft 1422 when the suction nozzle 1423 sucks the head card and places the head card is greater than 90°.

[0024] The rotating shaft 1422 is installed with a suction nozzle mounting plate 1425 , the suction nozzle 1423 is installed on the suction nozzle mounting plate 1425 , the suction nozzle mounting plate 1425 is connected to a card sticking lifting power source 1426 , and the card sticking lifting power source 1426 is connected to the rotating shaft 1422 .

[0025] like Figure 4 As shown, an axially extending limiting groove 1427 is provided on the suction nozzle mounting plate 1425, and the suction nozzle 1423 is adjustably fixed in the limiting groove 1427.

[0026] Hopper part: The hopper 141 is composed of an upper support member 1411, a lower support member 1412, an upper limit member 1413, and a horizontal limit member 1414. The upper support platform on the upper support member 1411 is used to support the upper header card, and the lower support platform on the lower support member 1412 is used to support the lower header card. The two are parallel to each other and extend in the first direction. The upper support member 1411 and the upper limit member 1413 form an upper channel 1415 for the upper header card to stand upright and be arranged along the first direction; a lower channel 1416 is formed between the bottom of the upper support member 1411 and the lower support member 1412 for the lower header card to stand upright and be arranged along the first direction. As one embodiment, a limit plate 1424 is also provided. The limit plate 1424 partially blocks the upper channel 1415 and the lower channel 1416 so that the upper and lower header cards are blocked and limited by the limit plate 1424 and can be sucked and removed by the suction nozzle 1423.

[0027] Card taking mechanism part: The card taking mechanism 142 is arranged between the silo 141 and the workbench 13. The rotating shaft 1422 is connected to the rotating power source 1421. The rotating power source 1421 can be a motor or an electric cylinder or connected to a conventional setting in the field such as a synchronous pulley belt, a synchronous chain, and a synchronous gear. The rotating shaft 1422 is connected to a number of suction nozzles 1423 arranged horizontally and connected to a negative pressure source. The arranged suction nozzles 1423 correspond to at least the upper head card and the lower head card position respectively. When the rotating power source 1421 drives the rotating shaft 1422 to rotate, the suction nozzle 1423 swings accordingly, and when it reaches the outlet end of the upper channel 1415 and the lower channel 1416, it uses the negative pressure to suck the head card, and then continues to swing to place the head card on the bag body on the workbench 13, and repeats this process.
