Description

Technical Field

[0001] The utility model relates to the technical field of finger sleeve packaging machines, in particular to a clamping device for finger sleeve packaging machines. Background Art

[0002] In the current medical finger sleeve packaging industry, the degree of automation of packaging equipment is increasing, but there are still some technical challenges. Among them, the automatic packaging of finger sleeves is a key link, which is directly related to packaging efficiency and product quality. During operation, traditional finger sleeve packaging machines often rely on the spacing of the finger sleeves on the fixed finger membrane. These spacings are usually set according to the minimum spacing or standard size of the finger sleeves during design. However, due to the changing market demand and the rich variety of products, the size of the finger sleeves and the design of the packaging bags are also showing a trend of diversification. This makes it difficult to match the gap between the finger sleeves and the packaging bags, especially when producing different models of finger sleeves, the problem is more prominent.

[0003] Specifically, when the packaging machine gripper grabs the finger sleeve and feeds it into the packaging bag, if the spacing between the grippers does not match the spacing between the packaging bags, the finger sleeves may not be placed properly, causing the finger sleeves in the packaging bag to be arranged at the dividing point of the packaging bag. In this case, once the subsequent bag cutting process begins, the finger sleeves will be cut, resulting in packaging failure, and the spacing parameters of the grippers need to be readjusted before the operation can be performed. This not only reduces packaging efficiency, but also increases production costs, affecting the overall market competitiveness of the product.

[0004] Therefore, we urgently need to design a gripping device for a finger sleeve packaging machine that can adaptively adjust the distance between the grippers according to the distance between the finger sleeves and packaging bags of different models. Utility Model Content

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the utility model provides a clamping device for a finger sleeve packaging machine that can adaptively adjust the distance between clamping jaws. The clamping device can automatically adjust the distance between finger sleeves and packaging bags of different models, thereby ensuring the precise positioning and neat arrangement of the finger sleeves during the packaging process.

DETAILED DESCRIPTION

[0027] The present invention will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0028] like Figure 1-8 As shown, the clamping device for the finger sleeve packaging machine includes a PLC controller, a packaging bag spacing identification device 2 and a clamping mechanism 3, which also includes two parallel transmission lines, namely a finger film feeder 1 for providing finger films and a packaging bag feeder 5 for providing packaging bags 6. The clamping mechanism 3 is installed between the two transmission lines through a connecting plate 7, and its purpose is to clamp the finger film on the finger film feeder 1 and load it into the packaging bag 6 on the packaging bag feeder 5. Specifically, the clamping mechanism 3 includes a base frame 31, a rotating shaft 32 and a mechanical clamp 33. The base frame 31 is installed on the connecting plate 7, and the rotating shaft 32 is rotatably arranged on the base frame 31. A plurality of mechanical clamps 33 are provided, which are evenly spaced along the length direction of the rotating shaft 32. The rotating shaft 32 controls the direction of the mechanical clamp 33 by rotating, wherein the rotating shaft 32 also includes a device for driving its rotation, which can be a motor, a rotating cylinder 321, etc. The motor or the rotating cylinder 321 is controlled to start and stop rotation through the PLC controller. The connecting plate 7 is also provided with a mechanism that can drive the clamping mechanism 3 to reciprocate between the two transmission lines, such as Figure 8 As shown, the mechanism is a linear reciprocating motion mechanism 8, which can adopt a linear slide platform, a screw platform, a linear motor and a slide slider matching structure, and a belt and a slide slider matching structure as shown in the figure. This is a conventional technology and will not be elaborated here.

[0029] In addition, the number of mechanical grippers 33 should be set according to the finger film and matched therewith.

[0030] Generally, the model of finger film is fixed, and it is formed by mold processing. The common ones are 5-finger, 6-finger and 8-finger. In the processing of finger film, except for the finger sleeve part, the rest of the parts are waste, so there is serious waste. In order to save materials, the finger sleeves are placed next to each other, so that the waste between adjacent finger sleeves is reduced, which can further save costs. However, the packaging bags on the market or provided by third parties are of different sizes and widths, which makes the spacing between finger films and packaging bags inconsistent. After changing the model of packaging bags, it is necessary to correct and debug parameters through the PLC controller, which is not only cumbersome, but also affects production efficiency.

[0031] In order to solve this problem, we set up a packaging bag spacing recognition device 2 to collect the marks on the packaging bags, so as to determine the distance between adjacent packaging bags; the PLC controller receives the data collected by the packaging bag spacing recognition device 2, and controls the component 4 for adjusting the distance between the mechanical clamps to adjust the distance between the mechanical clamps 33, so that the distance between the mechanical clamps 33 is the same as the distance between the packaging bags 6, so as to meet the production needs, wherein the packaging bag spacing recognition device 2 is arranged on the finger film feeder 1, close to the position of the packaging bag 6 reel, the packaging bag spacing recognition device 2 is an image acquisition and recognition device, in this embodiment, an industrial camera is preferably used as the recognition device, when the packaging bag 6 passes by the industrial camera, the industrial camera can recognize the mark on it, so as to determine the distance between two adjacent marks, and then feed back the collected data to the PLC controller, the mark on the packaging bag 6 mentioned here refers to the bar code, pattern, and other eye-catching marks on the packaging bag 6 that can be used for spacing judgment.

[0032] like Figure 3-7As shown, specifically, the component 4 for adjusting the spacing between the mechanical clamps includes a shaft sleeve 41, a tubular shaft 43 and a driving motor 44, the same number as the mechanical clamps 33, wherein the shaft sleeve 41 is slidably mounted on the rotating shaft 32, and the rotating shaft 32 and the shaft sleeve 41 may be connected by a sliding spline, or other structures may be adopted, such as: the rotating shaft 32 is a polygonal shaft, and the inner ring of the longitudinal section of the shaft sleeve 41 is also a polygonal shape adapted thereto. The purpose of setting this structure is to allow the sleeve 41 to slide along the axial direction (or length direction) of the rotating shaft 32, but not to rotate relative to the rotating shaft 32. Furthermore, when the component 4 for adjusting the spacing between the mechanical clamps is set, the mechanical clamps 33 are installed on the sleeve 41 instead. The mechanical clamps 33 and the sleeve 41 are in a one-to-one correspondence. Each mechanical clamp 33 is respectively and correspondingly installed on the outer wall of the sleeve 41. A pin 42 is provided at a position opposite to the mechanical clamp 33 on the outer wall of the sleeve 41. The pin 42 is radially arranged along the outer wall of the sleeve 41. A tube shaft 43 is sleeved on each sleeve 41. Both ends of the tube shaft 43 are rotatably connected to the base frame 31. A plurality of notches 431 that pass through the top of the tube shaft 43 are provided at the position corresponding to the tube shaft 43 and the mechanical clamp 33. The notches 431 are also in a one-to-one correspondence with the mechanical clamp 33. The notches 431 allow the connection between the mechanical clamp 33 and the sleeve 41 to move circumferentially and axially along the tube shaft 43.

[0033] At this time, the relationship between the sleeve 41, the tube shaft 43 and the rotating shaft 32 is: the rotating shaft 32 is located at the innermost part, the sleeve 41 is sleeved on the rotating shaft 32, and the tube shaft 43 is sleeved on the sleeve 41, both ends of the tube shaft 43 are rotatably matched with the base frame 31, the sleeve 41 and the tube shaft 43 are slidably rotatably matched, and one end of the rotating shaft 32 is fixedly connected to the rotating end of the rotating cylinder 321, and the other end is rotatably matched with the inner wall of the end of the tube shaft 43 through a bearing.

[0034] It should also be noted that an inclined adjustment hole 432 penetrating the bottom of the tube shaft 43 is provided at a position corresponding to the tube shaft 43 and the pin rod 42. The adjustment hole 432 and the pin rod 42 are also in a one-to-one correspondence. The pin rod 42 is placed in the adjustment hole 432 and slides therewith. The tube shaft 43 is rotated to rotate the adjustment hole 432 together, thereby driving each pin rod 42 to slide. The pin rod 42 is connected to the sleeve 41, which will drive the sleeve 41 to slide along the rotating shaft 32. Each sleeve 41 is adjusted at equal intervals.

[0035] The driving motor 44 is disposed on the base frame 31 , and the driving motor 44 is transmission-connected to the tube shaft 43 . In this embodiment, the rotating shaft of the driving motor 44 is directly connected to the tube shaft 43 via a coupling.

[0036] In order to reduce the wear caused by sliding between the pin 42 and the adjustment hole 432 , a rotating washer 422 is sleeved on the pin body 421 . The pin body 421 is fixed on the sleeve 41 . The diameter of the rotating washer 422 is slightly smaller than the diameter of the inclined adjustment hole 432 .

[0037] Specific reference Figure 7 Regarding the equidistant adjustment of the pin rod 42 by the adjustment hole 432, the structure of the adjustment hole 432 shown in the figure can be adopted. In the figure, the outermost adjustment hole 432 is used as the reference point. The adjustment hole 432 does not need to be set tilted. When the pipe shaft 43 rotates, the pin rod 42 located in the adjustment hole 432 does not produce axial displacement. The other adjustment holes 432 except the adjustment hole 432 are tilted, and the tilt angle forms a certain angle with the axis of the pipe shaft 43, so that the spacing between one end point of each adjustment hole 432 on the same side is a, and the spacing between one end point on the other side is b, and a is not equal to b.

[0038] Of course, the adjustment holes 432 may also be distributed in a fan shape, so that the adjustment hole 432 in the middle is not arranged tilted, and the adjustment holes 432 on both sides thereof are arranged in a fan shape.

[0039] In order to ensure the safety of the production process, the device is also provided with a protective shell (not shown in the figure). The shell cover is arranged at the processing position of the finger sleeve packaging machine. The PLC controller is integrated on the shell. The PLC controller is connected to the electrical components of the device and can coordinate and control its operation.

[0040] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, several modifications, improvements and substitutions can be made, 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.
