Description

Technical Field

[0001] The utility model relates to the technical field of feeding packaging bag buckles, in particular to a packaging bag feeding device and automatic buckle pressing equipment. Background Art

[0002] At present, in order to improve the convenience of using the packaging bag, a hand buckle is added to the bag surface of some packaging bag products. In the process of using the packaging bag, the hand buckle can be added to improve the strength and comfort of the packaging bag. In the prior art, in order to improve efficiency, a buckle machine is generally used to buckle the hand buckle on the packaging bag. Therefore, the current buckle machine performs automatic buckling through a bag loading mechanism-a buckle loading mechanism and a buckle pressing mechanism. However, the bag loading mechanism of the existing buckle pressing machine generally uses a bag hanging rod to hang the packaging bag to be buckled, and pushes the packaging bag to the side of the buckle pressing station through the bag pushing mechanism. At present, the bag is hung by passing the bag hanging rod through the through hole 901 of the packaging bag. In actual production, the through hole 901 of the packaging bag is generally elliptical or elliptical in shape. When the bag hanging rod is passed through, the outer peripheral surface of the bag hanging rod generally contacts the upper inner wall and the side inner wall of the through hole 901, which causes the part of the packaging bag above the through hole 901 to be easily tilted. In this state, multiple packaging bags will be difficult to separate, resulting in frequent problems of sticking bags, multiple bags at a time, or bags not being adsorbed during the bag loading process. Secondly, the number of bag hanging rod groups in the existing bag loading mechanism is limited, resulting in high frequency of manual bag loading and long machine downtime when loading bags.

[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0040] When the embodiments of the present invention mention ordinal numbers such as "first" and "second", unless they do express the meaning of order according to the context, they should be understood as being merely for distinction.

[0041] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] like Figure 1 , Figure 2 As shown, a packaging bag loading device comprises a bag loading mechanism 1, a bag pushing mechanism 2 arranged on the bag loading mechanism 1, the bag loading mechanism 1 is provided with a bag hanging rod group 122 for hanging packaging bags 9; the bag pushing mechanism 2 comprises a bag pushing frame 21, a bag pushing component 22 arranged on the bag pushing frame 21 and a bag suction component 23 arranged at the end of the bag pushing frame 21, the bag pushing component 22 is used for pushing the packaging bag 9 to move along the bag hanging rod group 122 to the end, and the bag suction component 23 is used for sucking the packaging bag 9 located at the front end of the bag hanging rod group 122; the bag pushing frame 21 is also provided with a bag dividing component above the bag hanging rod group 122, and the bag dividing component is used for inserting between the packaging bags to separate the packaging bags and adjust the posture to the posture of the end packaging bag. The embodiment of the utility model hangs multiple packaging bags on the bag loading mechanism, and uses the bag pushing mechanism to realize the displacement of the packaging bags on the bag hanging rod group, and uses the bag suction component to absorb and load the packaging bags when moving to the end, thereby realizing automatic loading of the packaging bags. In addition, during the process of the packaging bags moving to the end, the present solution adds a bag dividing component, so that the bag dividing component part inserted between the packaging bags can straighten the part of the packaging bags above the through hole, so that it is convenient for the packaging bags to be adsorbed during the subsequent bag loading and prevent the bag from sticking, thereby ensuring the efficiency of bag loading.

[0043] In the embodiment of the utility model, the bag pushing assembly 22 includes a bag pushing movable seat 211 that can move along the bag pushing frame 21 and a bag pushing plate 212 that can move up and down and is arranged on the bag pushing movable seat 211, and when the bag pushing plate 212 is located at the uppermost position, the lowermost end of the bag pushing plate 212 is higher than the upper side of the packaging bag 9 hung on the bag hanging rod group 122. The simple structural design can meet the continuous bag pushing work, and the bag pushing assembly 22 mainly pushes the packaging bag at the rear side of the packaging bag on the bag hanging rod group 122. In order to facilitate the forward pushing of the bag pushing assembly 22, after the bag hanging rod group 122 is supplemented with a new batch of packaging bags, the bag pushing plate 212 of the bag hanging rod group 122 can move from the upper side of the packaging bag to the rear side of the packaging bag to keep the bag pushing operation smooth.

[0044] In addition, in order to maintain stability during the bag pushing process, the bag pushing plate 212 includes a first bag pushing plate and a second bag pushing plate, and the first bag pushing plate and the second bag pushing plate are respectively located on both sides of the bag hanging rod group 122 after being moved down. Since the packaging bag is relatively wide, it is equivalent to pushing the rear side of the packaging bag from both sides to make it move forward.

[0045] In this solution, the bag suction assembly 23 includes a suction rod assembly 231 and a driving assembly for driving the suction rod assembly 231 to move. The suction rod assembly 231 is opposite to the end of the bag hanging rod assembly 122. When the packaging bag moves to the end, the suction rod assembly 231 moves toward the packaging bag, naturally sucking the frontmost packaging bag, and resetting the suction rod assembly 231, so that the packaging bag is sucked away, completing the loading.

[0046] In addition, in order to separate the multiple packaging bags at the end so that the frontmost one can be easily adsorbed, the bag suction assembly 23 also includes a bag separation air nozzle 232 arranged on the bag pushing frame 21 and opposite to the end of the bag hanging rod group 122.

[0047] like Figures 3 to 7 As shown, in this scheme, the specific structure of the bag dividing assembly is as follows: the bag dividing assembly is close to the end of the bag hanging rod group 122, and the bag dividing assembly includes a driving member 141 arranged on the bag pushing frame 21, a movable seat 142 arranged on the driving member 141, and a bag dividing lever 143 arranged on the movable seat 142 and extending downward, the driving member 141 is used to drive the movable seat 142 and the bag dividing lever 143 to reciprocate along the bag-up direction; the bag dividing lever 143 is hinged on the movable seat 142, and a limiting portion 1432 is provided on the bag dividing lever 143, the bag dividing lever 143 can rotate relative to the movable seat 142 in the bag-up direction, and after the bag dividing lever 143 is inserted into the gap of the packaging bag, the limiting portion 1432 is used to limit the bag dividing lever 143 from rotating in the direction away from the bag-up direction. During the bag pushing process, the bag dividing lever 143 is inserted between the multiple packaging bags 9 of the bag loading mechanism to separate the packaging bags, and the driving member 141 is used to drive the bag dividing lever 143 forward (in the bag loading direction) so that the bag dividing lever portion inserted between the packaging bags can straighten the portion of the packaging bag above the through hole to adjust the posture of the packaging bag so that it is easy to be adsorbed during the subsequent bag loading and prevent the bag from sticking. In addition, the bag dividing lever 143 of this solution adopts the combination of hinge and limiter 1432, so that when the driving member 141 drives the bag dividing lever 143 to reset (in the opposite direction of the bag loading direction), the bag dividing lever is pushed open by the upper part of the packaging bag and inserted into the gap between the multiple packaging bags. When the driving member drives the bag dividing lever forward, the limiter restricts the bag dividing lever from rotating to straighten the packaging bag located in front of the bag dividing lever.

[0048] Specifically, in this solution, the lower end of the bag dividing lever 143 is an insertion end 1431. The main function of the insertion end 1431 is to extend into the gap between multiple packaging bags, thereby separating multiple packaging bags on the bag hanging assembly into two batches, one batch located at the rear side of the insertion end 1431, and the other batch located at the front side of the insertion end 1431, and the bag dividing lever 143 is used to adjust the posture of the upper end of the batch of packaging bags located at the front side of the insertion end 1431 to straighten the upper side of the packaging bags.

[0049] In the embodiment of the utility model, the insertion end 1431 is a tip with a width gradually decreasing from top to bottom, and this shape is conducive to its insertion into the gap between multiple packaging bags. Specifically, since the upper ends of the multiple packaging bags on the bag hanging rod are easily fitted together, and the degree of fitting will also cause larger gaps in some positions, and the bag-dividing lever 143 will naturally return to a hanging posture due to its own weight. In this scheme, the packaging bag on the lower side is pushed by the bag pushing mechanism, and the relative bag-dividing lever 143 moves forward, or the driving member 141 drives the bag-dividing lever 143 to move backward, multiple bags are inserted into the bag hanging rod 143. The upper end of the bag will contact the rear side of the insertion end 1431 and push the insertion end 1431 to rotate. In the attached figure of this scheme, it rotates counterclockwise, so it can be regarded as the insertion end 1431 resting on the upper side of multiple packaging bags, and the insertion end 1431 always maintains a tendency to return to a hanging posture. When encountering a larger gap, the insertion end 1431 will naturally be inserted into the gap, thereby separating multiple packaging bags. The principle is equivalent to the bag dividing lever 143 stroking along the upper sides of multiple packaging bags. When a larger gap is found, the sharper insertion end will naturally be inserted into the gap.

[0050] Specifically, in the embodiment of the utility model, the side of the insertion end 1431 facing the bag loading direction is a straight side surface, which is conducive to straightening the part of the bag on the side located above the through hole 901 when pushing a batch of bags in front of the bag separation lever 143 to adjust the posture.

[0051] In addition, the side of the insertion end 1431 facing away from the bag-up direction is an inclined side surface, and the inclined side surface and the straight side surface together form an insertion end 1431 whose width gradually decreases from top to bottom. The structure of the inclined side surface is conducive to forming a tip and facilitates the bag-dividing lever 143 to give way.

[0052] In this solution, the limiting portion 1432 is located near the upper side of the bag-dividing lever 143, and when the bag-dividing lever 143 rotates along the hinge until the limiting portion 1432 abuts against the moving seat 142, the bag-dividing lever 143 is limited to continue rotating in this direction. Specifically, the limiting portion 1432 is a protrusion extending from the inner side of the bag-dividing lever 143. It has a simple structure, and is convenient for limiting the backward rotation of the limiting portion 1432 due to the reverse force of the front packaging bag when the driving member 141 drives the limiting portion 1432 to move forward.

[0053] In the embodiment of the utility model, the bag-dividing levers 143 are provided on both sides of the movable seat 142. The force on both sides is kept parallel. Of course, multiple bag-dividing levers 143 can also be adjusted according to the width of the packaging bag or the through hole 901.

[0054] In this solution, the movable seat 142 includes a seat body and sidewalls 1421 located on both sides of the seat body and extending backwards, the two bag-dividing levers 143 are respectively hinged on the sidewalls 1421 on both sides, and the limiting parts 1432 on the two bag-dividing levers 143 are both located at the rear side of the sidewalls 1421 and opposite to the corresponding sidewalls 1421. The structure is simple and easy to manufacture.

[0055] In addition, the present solution drives the bag dividing rod 143 to reciprocate through the driving member 141 to assist in adjusting the posture of the packaging bag on the front side. After completion, the bag dividing rod 143 is translated to the front end, and the bag dividing rod 143 is moved backward and reset to be reinserted into the gap between the packaging bags on the original rear side, thereby separating and realizing circulation.

[0056] like Figures 8 to 16As shown, in the embodiment of the utility model, bag-supporting guide blocks are additionally provided on the outer periphery of the rod heads of the first hanging rod and the second hanging rod. The bag-supporting guide blocks increase the contact area and angle with the through hole of the packaging bag. When the packaging bag is pushed to the upper bag, it will inevitably move to contact the bag-supporting guide blocks, so that the bag-supporting guide blocks contact the corner position inside the through hole, simulating the effect of pulling the packaging bag from an oblique direction and a side direction, so that the portion of the packaging bag above the through hole can be easily adjusted from a tilted state to a vertical or nearly vertical posture. Specifically, the bag hanging rod group 122 includes at least two first hanging rods 1221 and second hanging rods 1222 arranged side by side and horizontally, and the ends of the first hanging rod 1221 and the second hanging rod 1222 are respectively provided with a first rod head 12211 and a second rod head 12221, and the first hanging rod 1221 and the second hanging rod 1222 are used to hang the packaging bag to be buckled through the through hole 901 of the packaging bag; in the automatic buckling machine, the packaging bag will be gradually pushed from the rod body of the first hanging rod 1221 and the second hanging rod 1222 to the rod head position through the bag pushing mechanism, and finally be adsorbed at the rod head position. In order to ensure the smooth buckling of the upper bag, it is necessary to ensure that only one packaging bag is adsorbed at a time during adsorption. Therefore, it is very necessary to perform certain separation operations before the packaging bag is adsorbed. The outer peripheries of the first rod head 12211 and the second rod head 12221 are respectively provided with bag-supporting guide blocks 1225 for supporting the packaging bag 9. When the packaging bag 9 moves to the first rod head 12211 and the second rod head 12221, the inner wall of the through hole 901 of the packaging bag will contact the outer periphery of the bag-supporting guide blocks 1225 to be supported. The bag-supporting guide blocks 1225 increase the contact area and angle with the through hole 901 of the packaging bag. When the packaging bag is pushed to the upper bag, it will inevitably move to contact with the bag-supporting guide blocks 1225, so that the bag-supporting guide blocks 1225 contact the corner position inside the through hole 901, simulating the effect of pushing and pulling the packaging bag from the oblique direction and the side direction, so that the part of the packaging bag above the through hole can be easily adjusted from the tilted state to the vertical or nearly vertical posture.

[0057] Of course, in the embodiment of the utility model, the first hanging rod 1221 and the second hanging rod 1222 can also be processed into an integral hanging rod, that is, the first hanging rod 1221 and the second hanging rod 1222 are an integral structure, and the overall structure is a flat single hanging rod.

[0058] In the embodiment of the utility model, the bag-supporting guide blocks 1225 on the first hanging rod 1221 and the second hanging rod 1222 are both arranged on the outward side of the first rod head 12211 and the second rod head 12221, and the two bag-supporting guide blocks 1225 are arranged at an angle relative to each other. The outer peripheral surfaces of the bag-supporting guide blocks 1225 arranged opposite to each other on both sides jointly form an effect of enlarging the outer diameters of the first rod head 12211 and the second rod head 12221, that is, only when the packaging bag moves to the corresponding position will it be supported by the bag-supporting guide blocks 1225, which has the advantage of facilitating the movement of the packaging bag at the rod body.

[0059] Furthermore, in the embodiment of the utility model, the outer peripheral surface of the bag support guide block 1225 is arc-shaped and faces the corner direction of the packaging bag through hole 901. This solution mainly adds an outwardly protruding bag support guide block 1225 on the outer periphery of the first rod head 12211 and the second rod head 12221, and faces the corner of the through hole 901, so that when the packaging bag moves to contact with the bag support guide block 1225, a pull is formed, so that the part of the packaging bag above the through hole is easily adjusted from a tilted state to a vertical or nearly vertical posture.

[0060] In the embodiment of the utility model, the outer peripheral surface of the bag support guide block 1225 is a concave-convex surface. When multiple packaging bags are moved to the bag support guide block 1225, they are naturally separated by the concave and convex surfaces on the surface thereof, thereby forming a better separation effect.

[0061] Specifically, in this scheme, if Figure 8 and Fig. 9 As shown, the surface of the bag supporting guide block 1225 may be provided with a plurality of convex points, or structures such as patterns or grooves to form an uneven surface, so that the packaging bags will naturally be separated and arranged along the uneven surface.

[0062] In the embodiment of the utility model, the bag support guide block 1225 on the first rod head 12211 and the second rod head 12221 are both detachably connected. The structure is simple and easy to install.

[0063] In addition, in this embodiment, oblique guide structures 12250 are provided on both sides of the bag support guide block 1225, and the oblique guide structures 12250 are inclined along the length direction of the bag hanging rod group 122. Through the oblique guide structures 12250, the packaging bag can smoothly transition to the surface of the bag support guide block 1225 when moving along the length direction of the hanging rod.

[0064] In this solution, in order to form a better supporting effect, the two bag supporting guide blocks 1225 are arranged at an angle relative to each other. The most ideal angle is toward the upper corners on both sides of the through hole of the packaging bag, but in order to facilitate the adaptation of packaging bags of various specifications, the first rod head 12211 and the second rod head 12221 are further connected to the lower side of the adjusting block 1226, and the adjusting block 1226 is provided with connecting positions on both sides, and the first rod head 12211 and the second rod head 12221 are respectively installed with the connecting positions to adjust the relative angle. Its specific structure is: the lower side of the first rod head 12211 and the second rod head 12221 are provided with concave positions for the adjusting block 1226 to be embedded, and the concave positions are provided with connecting holes, and the connecting positions on both sides of the adjusting block 1226 are long holes. In this solution, screws are used as connectors, which are inserted through the long holes and locked into the connection holes on the lower side of the first rod head 12211 or the second rod head 12221 for fixed installation. After the first rod head 12211 or the second rod head 12221 is rotated to a certain angle, the screw connector can be installed obliquely through the long holes, thereby achieving an angle adjustment effect within a certain range, so that more specifications of packaging bags can be adapted for adjustment and use.

[0065] Moreover, the bag hanging rod set 122 also includes a connecting rod 1223, and connecting parts are provided on both sides of the front end of the connecting rod 1223, and the first hanging rod 1221 and the second hanging rod 1222 are both connected to the connecting parts. The connecting rod 1223 is installed side by side with the first hanging rod 1221 and the second hanging rod 1222 on both sides.

[0066] like Figures 17 to 19 As shown, the embodiment of the utility model improves the bag-loading structure of the traditional single-group bag-hanging assembly, adopts multiple groups of bag-hanging assemblies in conjunction with a rotating switching platform, and realizes uninterrupted bag supply on the automatic buckle machine. When the rotating switching platform drives one group of bag-hanging assemblies to rotate to the bag-loading station for bag supply, the other group of bag-hanging assemblies must be in an idle position, so there is enough time to facilitate manual replenishment of packaging bags, and it does not affect the bag supply to the automatic buckle machine, which greatly improves efficiency. Specifically, the bag-loading mechanism 1 includes a first frame 10, a rotating switching platform 11 arranged on the first frame 10, a first driving assembly 111 that drives the rotating switching platform 11 to rotate, and at least two groups of bag-hanging assemblies 12 arranged on the rotating switching platform 11, the bag-hanging assemblies 12 are used to hang packaging bags 9, one side of the first frame 10 is a bag-loading station opposite to the bag pushing mechanism 2, and the rotating switching platform 11 is used to rotate one group of bag-hanging assemblies 12 to the bag-loading station.

[0067] In the embodiment of the utility model, the present solution drives the bag hanging assembly 12 to rotate by the rotating switching platform 11, ensuring that only one bag hanging rod group 122 is located at the bag loading station, and the rest are naturally rotated out of the bag loading station, at which time the packaging bags to be buckled can be added through their free ends. The structure is simple, and the rotating switching platform 11 is used for rotation switching, and multiple stations are naturally circulated.

[0068] Therefore, in the embodiment of the utility model, the rotating switching platform 11 is utilized to rotate along its own rotation axis to switch the position of the bag hanging components 12 on its circumference. Therefore, the rotation angle of each rotating switching platform 11 can be set according to the number of bag hanging components 12. For example, when there are two rotating switching platforms 11, the two rotating switching platforms 11 are arranged at 180° relative to each other. At this time, the rotating switching platform 11 only needs to rotate 180° each time to switch different bag loading stations at the bag loading station.

[0069] The rotating switching platform 11 is provided with four groups of bag hanging assemblies 12, and the four groups of bag hanging assemblies 12 are evenly distributed along the circumference of the rotating switching platform 11. That is, the four bag hanging assemblies 12 are arranged at 90° intervals, so that the rotating switching platform 11 can be switched each time by rotating 90°, and the three groups of bag hanging assemblies 12 on the outside are in an idle state, which is convenient for manual replenishment of packaging bags to be buckled.

[0070] In this embodiment, the specific structure of the bag hanging assembly 12 is as follows: the bag hanging assembly 12 includes a mounting seat 121 and a bag hanging rod group 122, one end of the bag hanging rod group 122 is connected to the mounting seat 121, and the other end is a free end for the handle through hole 901 on the packaging bag 9 to pass through.

[0071] In order to make full use of the space, in this embodiment, the bag hanging assembly 12 further includes a positioning block 123 mounted on the mounting seat 121 and extending along the length direction of the bag hanging rod group 122. The positioning block 123 is used to block and limit the initial position of the packaging bag when it is hung, so that the reset bag pushing mechanism can be located at the rear side of all packaging bags, which is relative to the bag loading station. Similarly, it is also convenient for the rotating switching platform 11 to rotate the bag hanging assembly 12 after replenishing materials to the bag loading station to prevent the packaging bag from interfering with the bag pushing mechanism.

[0072] Specifically, in the embodiment of the utility model, the specific structure of the positioning block 123 is as follows: the positioning block 123 is detachably mounted on the lower side of the mounting seat 121, and includes a connecting plate 1231 connected to the mounting seat 121 and a baffle 1232 provided at the end of the connecting plate 1231 and extending downward, and the baffle 1232 and the connecting plate 1231 form an L-shaped positioning block 123. It has a simple structure, is easy to install and use, and the installation position of the connecting plate 1231 can be adjusted according to needs, thereby adjusting the distance of its limit.

[0073] In the embodiment of the utility model, in order to improve the stability of the rotary switching platform 11 after rotation, a positioning component 14 for limiting the rotation of the rotary switching platform 11 is further provided at the bag loading station on the first frame 10. When the rotary switching platform 11 is switched, the positioning component 14 can be further positioned by correspondingly mounting the lower side of the bag hanging assembly 12 on the rotary switching platform 11 to ensure that the movement is in place and the accuracy of subsequent processing is guaranteed.

[0074] Specifically, in this solution, the first embodiment of the positioning component 14 is: the mounting seat 121 partially extends to the outside of the rotating switching platform 11, and the positioning component 14 includes a detection seat 141 arranged on the first frame 10 and a positioning column 142 on the lower side of the extending end of the mounting seat 121, and the detection seat 141 is provided with a detection port for the positioning column 142 to slide into. Through the detection port on the detection seat 141, when the rotating switching platform 11 is switched, the lower side of the corresponding bag hanging assembly 12 is provided with a positioning column 142 extending downward, and when the positioning column 142 slides into the detection port, the system can detect that it has moved into place. Of course, in this solution, the first driving component 111 that drives the rotating switching platform 11 to rotate can use a servo motor, which can drive the rotating switching platform 11 to rotate accurately, and cooperate with the positioning component 14 in this embodiment to achieve an additional positioning guarantee. In this solution, the detection seat 141 can be implemented by infrared detection.

[0075] In this solution, the second embodiment of the positioning component 14 is: a positioning hole is provided on the lower side of the extended end of the mounting seat 121, and the positioning component 14 includes a pin seat provided on the first frame 10 and a positioning pin provided on the pin seat, and the positioning pin can be inserted into the positioning hole. Of course, for the convenience of use, the pin seat can be connected to a cylinder, a motor, etc. to achieve automatic insertion and limiting, so as to prevent displacement caused by vibration during the bagging process, and improve the position accuracy of subsequent processes.

[0076] In addition, the utility model is also convenient for integrated installation. Specifically, the first frame 10 is also provided with a frame mounting column 15 extending upward from the middle of the rotating switching platform 11, and the frame mounting column 15 is used to be installed with the bag pushing mechanism 2. It has a simple structure and is easy to assemble and use.

[0077] The utility model also provides an automatic buttoning device, comprising a buttoning machine, one side of the buttoning machine is provided with the above-mentioned packaging bag loading device.

[0078] The embodiment of the utility model hangs multiple packaging bags on the bag loading mechanism, and uses the bag pushing mechanism to realize the displacement of the packaging bags on the bag hanging rod group, and uses the bag suction component to absorb and load the packaging bags when moving to the end, thereby realizing automatic loading of the packaging bags. In addition, during the process of the packaging bags moving to the end, the present solution adds a bag dividing component, so that the bag dividing component part inserted between the packaging bags can straighten the part of the packaging bags above the through hole, so that it is convenient for the packaging bags to be adsorbed during the subsequent bag loading and prevent the bag from sticking, thereby ensuring the efficiency of bag loading.

[0079] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
