Description
Technical Field
[0001] The utility model relates to the technical field of manufacturing controlled glass bottles, and particularly relates to an automatic glass tube feeding machine for controlled glass bottles. Background Art
[0002] A controlled glass bottle is a kind of glass tube suitable for multiple industries, which is made from a long glass tube through processes such as cutting, sealing, and annealing. In the pharmaceutical packaging industry, controlled glass bottles are widely used in the packaging of various drugs such as oral liquids, injections, and vials. In the food packaging field, as a traditional beverage packaging container, the transparency and sterility of glass bottles make them an ideal choice for beverage packaging.
[0003] When the glass tube is cut and sealed to form a glass bottle, it is generally completed in a rotary forming machine. At this time, a glass tube feeding machine is required to timely supply the glass tube to the rotary forming machine to achieve continuous production of the rotary forming machine.
[0004] In the related art, the glass tube feeding machine generally includes a clamping jaw for clamping the glass tube and a feeding machine body that drives the clamping jaw to move in three-dimensional space and realizes the turning of the glass tube. When the clamping jaw clamps the glass tube from the auxiliary frame or the feeding machine body drives the glass tube to rotate, due to the long length and thin diameter of the glass tube, under the self-gravity of the glass tube and the moment of inertia generated during rotation, the glass tube is easily broken at the clamping jaw. Content of the Utility Model
[0005] In view of this, the utility model aims to provide an automatic glass tube feeding machine for controlled glass bottles to solve the problem that the glass tube is easily broken at the clamping jaw and improve the stability during the transfer of the glass tube.
[0006] To achieve the above object, the technical solution of the utility model is realized as follows:
[0007] An automatic glass tube feeding machine for controlled glass bottles includes a clamping jaw connected to the feeding machine body, and the clamping jaw includes:
[0008] A fixed jaw connected to the feeding machine body, a moving jaw with the same opening direction as the fixed jaw and capable of approaching or departing from the fixed jaw along a straight line, and an adjusting member for adjusting the distance between the moving jaw and the fixed jaw.
[0009] Further, the adjusting member connects the fixed jaw and the moving jaw and is configured such that when the feeding machine body drives the clamping jaw to rotate and the fixed jaw and the moving jaw are arranged in the vertical direction, the moving jaw is located above the fixed jaw.
[0010] Further, the adjusting member includes: a limiting rod, which is a straight rod, one end of which is fixedly connected to the fixed claw, and the remaining end passes through the moving claw, so that the moving claw is slidably connected along the limiting rod; a driving member, which connects the fixed claw and the moving claw to drive the moving claw to slide along the length direction of the limiting rod.
[0011] Further, the cross-section of the limiting rod is a circular surface, a triangular surface or a rectangular surface.
[0012] Further, the driving member is a cylinder or a hydraulic cylinder.
[0013] Further, the driving member includes:
[0014] a screw rod that is rotatably connected to the fixed claw, passes through the moving claw and is threadedly connected to the moving claw, and a driving motor that drives the screw rod to rotate;
[0015] The driving motor drives the screw rod to rotate in different rotation directions to make the moving claw approach or move away from the fixed claw.
[0016] Further, the driving motor is located on the side close to the fixed claw.
[0017] Compared with the prior art, the utility model has the following advantages:
[0018] In the automatic glass tube loading machine of the utility model, by setting a moving claw that can approach or move away from the fixed claw along a straight line, the distance between the two is adjusted. When clamping the glass tube, the distance between the fixed claw and the moving claw is adjusted by the adjusting member, so that the clamping claw can be connected to the glass tube within a larger span; during the transfer or rotation of the glass tube, the rigidity of the adjusting member itself can reduce the influence of the rotational inertia on the glass tube. It has the effect of reducing the risk of the glass tube breaking at the clamping claw and improving the stability of the glass tube during transfer.
[0019] By setting that when the fixed claw and the moving claw are arranged vertically, the moving claw is located above the fixed claw. When one end of the glass tube is facing the rotary bottle making machine, the glass tube needs to be inserted into the working station of the rotary bottle making machine. At this time, the clamping of the glass tube by the fixed claw is released, and the clamping of the glass tube by the moving claw is maintained. The adjusting member is started, and the adjusting member drives the moving claw to move towards the side close to the fixed claw, so as to realize inserting the glass tube into the rotary bottle making machine.
[0020] By setting the limiting rod, while realizing the sliding path of the moving claw, the limiting rod has good rigidity, which can better reduce the possibility of damage to the glass tube caused by the rotational inertia when the glass tube rotates, so as to improve the stability of the glass tube during rotation.
[0021] By setting the cross-section of the limit rod to different shapes, while ensuring the rigidity of the limit rod, when it is set to a circular cross-section, that is, when the limit rod is a cylinder, the friction between the limit rod and the moving claw can be reduced; when the limit rod has a triangular or rectangular surface, when the moving claw slides along the limit rod, relative rotation between the moving claw and the limit rod can be prevented, thereby further ensuring that the opening directions of the fixed claw and the moving claw are the same, and avoiding the generation of torsion on the glass tube by the moving claw and the fixed claw.
[0022] When the driving member is a cylinder, the distance between the moving claw and the fixed claw can be adjusted at a faster speed; when the driving member is a hydraulic cylinder, the distance between the moving claw and the fixed claw can be adjusted at a slower speed but with less inertia.
[0023] By setting the driving member as a screw rod and a driving motor, when adjusting the distance between the moving claw and the fixed claw, start the driving motor, and the output shaft of the driving motor drives the screw rod to rotate to achieve stable adjustment; and when the output shaft of the driving motor rotates in reverse to reduce the distance between the fixed claw and the moving claw, the glass tube can be stably and slowly inserted into the rotary bottle-making machine.
[0024] Set the driving motor on the side close to the fixed claw. When the upper tube machine body drives the clamping jaw to rotate, the weight difference on both sides of the rotating shaft of the upper tube machine body can be reduced, improving the stability and control accuracy during rotation.

[0035] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.
[0036] This embodiment relates to an automatic glass tube loading machine for control glass, aiming to solve the problem that the glass tube is prone to break at the clamping jaw 2 and improve the stability during the transfer of the glass tube.
[0037] In terms of the overall structure, the automatic glass tube loading machine for control glass includes a clamping jaw 2 connected to the loading machine body 1. As Figures 1 to 3 shown, the clamping jaw 2 includes: a fixed jaw 201 connected to the loading machine body 1, a movable jaw 202 with the same opening direction as the fixed jaw 201 and capable of approaching or departing from the fixed jaw 201 along a straight line, and an adjusting member 203 for adjusting the distance between the movable jaw 202 and the fixed jaw 201.
[0038] By setting the movable jaw 202 that can approach or depart from the fixed jaw 201 along a straight line, the distance between the two is adjusted. When clamping the glass tube, the distance between the fixed jaw 201 and the movable jaw 202 is adjusted through the adjusting member 203, so that the clamping jaw 2 is connected to the glass tube within a larger span; during the transfer or rotation of the glass tube, the rigidity of the adjusting member 203 itself can reduce the influence of the moment of inertia on the glass tube. It has the effect of reducing the risk of the glass tube breaking at the clamping jaw 2 and improving the stability during the transfer of the glass tube.
[0039] Based on the above overall introduction, in this embodiment, the loading machine body 1, as Figures 1 to 3As shown in the figure, it can drive the gripper 2 to move and rotate in three-dimensional space, that is, the upper tube machine body 1 can move up and down, left and right, and back and forth, and drive the gripper 2 to rotate with the central axis of the connecting shaft connecting the gripper 2 as the rotation axis. In this embodiment, the fixed jaw 201 is connected to the connecting shaft.
[0040] Based on the purpose of improving the stability during the transfer of the glass tube, in order to insert the glass tube into the working station of the rotary bottle making machine more stably, the adjusting member 203 connects the fixed jaw 201 and the moving jaw 202 and is configured such that when the upper tube machine body 1 drives the gripper 2 to rotate, the moving jaw 202 is located above the fixed jaw 201 when the fixed jaw 201 and the moving jaw 202 are arranged in the vertical direction.
[0041] By setting that when the fixed jaw 201 and the moving jaw 202 are arranged in the vertical state, the moving jaw 202 is located above the fixed jaw 201. When one end of the glass tube faces the rotary bottle making machine, the glass tube needs to be inserted into the working station of the rotary bottle making machine. At this time, release the clamping of the glass tube by the fixed jaw 201, keep the clamping of the glass tube by the moving jaw 202, start the adjusting member 203, and the adjusting member 203 drives the moving jaw 202 to move towards the side close to the fixed jaw 201 to realize inserting the glass tube into the rotary bottle making machine.
[0042] Specifically, the adjusting member 203 is a key component for adjusting the distance between the moving jaw 202 and the fixed jaw 201. Its first purpose is to ensure that the fixed jaw 201 and the moving jaw 202 adjust the distance between the moving jaw 202 and the fixed jaw 201 along a straight line and prevent the two from being misaligned. For this reason, the adjusting member 203 includes a limiting rod 2031 and a driving member 2032; the limiting rod 2031 is a straight rod, one end of which is fixedly connected to the fixed jaw 201, and the remaining end passes through the moving jaw 202, forming a sliding connection of the moving jaw 202 along the limiting rod 2031; the driving member 2032 connects the fixed jaw 201 and the moving jaw 202 to drive the moving jaw 202 to slide along the length direction of the limiting rod 2031.
[0043] By setting the limiting rod 2031, while realizing the limitation of the sliding path of the moving jaw 202, the limiting rod 2031 has good rigidity, and can better reduce the possibility of damage to the glass tube caused by the rotational inertia when the glass tube rotates, so as to improve the stability during the rotation of the glass tube.
[0044] It can be understood that on the basis of meeting the above purposes, the limiting rod 2031 can be set to different shapes; for example, the cross-section of the limiting rod 2031 is a circular surface, a triangular surface or a rectangular surface. By setting the cross-section of the limiting rod 2031 to different shapes, while ensuring the rigidity of the limiting rod 2031, when it is set to a circular cross-section, that is, when the limiting rod 2031 is a cylinder, the friction between the limiting rod 2031 and the moving claw 202 can be reduced; when the limiting rod 2031 has a triangular surface or a rectangular surface, when the moving claw 202 slides along the limiting rod 2031, relative rotation between the moving claw 202 and the limiting rod 2031 can be prevented, thereby further ensuring that the opening directions of the fixed claw 201 and the moving claw 202 are the same, and avoiding the generation of torsion on the glass tube by the moving claw 202 and the fixed claw 201.
[0045] Based on the purpose of adjusting the distance between the moving claw 202 and the fixed claw 201 along the length direction of the limiting rod 2031, as Figure 1 and Figure 3 shown, the driving member 2032 can have various setting forms. In this embodiment, the driving member 2032 is selected as a cylinder or a hydraulic cylinder. When the driving member 2032 is a cylinder, the distance between the moving claw 202 and the fixed claw 201 can be adjusted at a faster speed; when the driving member 2032 is a hydraulic cylinder, the distance between the moving claw 202 and the fixed claw 201 can be adjusted at a slower speed but with less inertia.
[0046] As an alternative other implementation manner, as Figures 1 to 2 shown, in this embodiment, the driving member 2032 includes: a screw rod 2032a rotatably connected to the fixed claw 201 and threadedly connected to the moving claw 202 through the moving claw 202, and a driving motor 2032b for driving the screw rod 2032a to rotate; the driving motor 2032b drives the screw rod 2032a to rotate in different rotation directions to make the moving claw 202 approach or move away from the fixed claw 201. By setting the driving member 2032 as the screw rod 2032a and the driving motor 2032b, when adjusting the distance between the moving claw 202 and the fixed claw 201, the driving motor 2032b is started, and the output shaft of the driving motor 2032b drives the screw rod 2032a to rotate to achieve stable adjustment; and when the output shaft of the driving motor 2032b rotates reversely to reduce the distance between the fixed claw 201 and the moving claw 202, the glass tube can be stably and slowly inserted into the rotary bottle making machine.
[0047] When the driving member 2032 is set as the screw rod 2032a and the driving motor 2032b, in order to make the clamping jaw 2 rotate more smoothly, the driving motor 2032b is located on the side close to the fixed claw 201. By setting the driving motor 2032b on the side close to the fixed claw 201, when the upper tube machine body 1 drives the clamping jaw 2 to rotate, the weight difference on both sides of the rotating shaft of the upper tube machine body 1 is reduced, and the stability and control accuracy during rotation are improved.
[0048] When the automatic glass tube loading machine described in this embodiment is in use, the distance between the fixed claw 201 and the moving claw 202 is adjusted by controlling the adjusting member 203. Then, the fixed claw 201 and the moving claw 202 are respectively controlled to clamp the glass tube. After the loading machine body 1 drives the clamping jaw 2 to rotate, the fixed claw 201 is adjusted to release the clamping of the glass tube. The adjusting member 203 drives the moving claw 202 and the glass tube to move toward the side close to the fixed claw 201, so as to insert the glass tube into the rotary tube making machine. By providing the moving claw 202 that can approach or move away from the fixed claw 201 along a straight line, the distance between the two is adjusted. When clamping the glass tube, the distance between the fixed claw 201 and the moving claw 202 is adjusted by the adjusting member 203, so that the clamping jaw 2 is connected to the glass tube within a larger span; during the transfer or rotation of the glass tube, the rigidity of the adjusting member 203 itself can reduce the influence of the moment of inertia on the glass tube. It has the effect of reducing the risk of the glass tube breaking at the clamping jaw 2 and improving the stability during the transfer of the glass tube.
[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
