Description

Technical Field

[0001] This utility model relates to a transportation device for glass products during the manufacturing process, specifically a storage silo and corresponding pipe supply mechanism, and an automatic pipe feeding machine for bottle making machines. Background Technology

[0002] The automatic tube feeder for bottle making machines is responsible for feeding the tubes (i.e., glass tubes) onto the chuck of the bottle making machine to ensure a continuous supply of tubes and a steady stream of raw materials, thus preventing production interruptions due to untimely material supply.

[0003] The existing automatic tube feeding mechanism for bottle making machines mainly includes a tube feeding mechanism and a tube transfer and insertion mechanism. The tube feeding mechanism includes a hopper and a lifting assembly. The hopper stores the tubes, and the lifting assembly raises the glass tubes in the hopper to a certain height for subsequent conveying. The tube transfer and insertion mechanism includes a transfer assembly and a tube inserter. The transfer assembly typically includes a cross slide and a robotic arm / nozzle mounted on the cross slide, used to transfer the tubes from the hopper one by one to the tube inserter, which then feeds the tubes onto the bottle making machine's chuck.

[0004] To ensure that the material pipes can be stored in an orderly manner and smoothly enter the subsequent conveying process, the material pipes in the silo are usually placed in multiple staggered layers (e.g., Figure 2 (as shown), and as Figure 1 As shown, a toothed plate 23 is installed at the bottom of the hopper. The toothed plate 23 is used to lock and restrict the bottom layer of material pipes, so as to prevent the material pipes from sliding in the hopper and becoming unstable when transferring the bottom layer of material pipes one by one, which would cause the transfer assembly to be unable to accurately grab the material pipes.

[0005] However, the method of using toothed plates 23 to position the bottommost material tube has certain problems in practical applications, mainly manifested in the fact that the changeover operation is relatively troublesome. The reason is that toothed plates 23 of corresponding specifications need to be replaced for material tubes of different diameters. Therefore, each changeover requires workers to disassemble and replace the toothed plates 23 of the corresponding specifications, which is quite cumbersome. This defect is particularly prominent when changing production frequently. Utility Model Content

[0011] As the further limitation of the utility model, the movable end of the rectangular plate is assembled with a rotating member in contact with the output end of the driving member.

[0012] As the further limitation of the utility model, the driving member includes a pneumatic cylinder fixed on the silo body through a pneumatic cylinder fixing plate, and the output end of the pneumatic cylinder is vertically upward and in contact with the rotating member.

[0013] As the other limitation of the utility model, the silo body includes a platform for placing the pipe, and a first limiting member and a second limiting member assembled on the platform for clamping the pipe; the first limiting member, the second limiting member and the platform constitute the pipe storage space.

[0014] The utility model also discloses a pipe supply mechanism, which comprises the pipe storage silo and a lifting assembly connected with the pipe storage silo and used for controlling the pipe storage silo to lift.

DETAILED DESCRIPTION

[0031] The preferred embodiments of the present application will be described below with reference to the drawings. It should be understood that the preferred embodiments described herein are only for explaining and understanding the present application, and are not intended to limit the present application.

[0032] The embodiment discloses a pipe storage bin 12, which is a container for storing pipes 22 in an automatic pipe feeding machine of a bottle making machine. Figures 3 to 6 As shown in the figure, the pipe storage bin 12 comprises a bin body and a pipe supporting assembly 6 assembled on the bin body.

[0033] The bin body has at least one pipe storage space, specifically, the bin body comprises a platform 1 for placing the pipes 22 and first limiting pieces 2 and second limiting pieces 3 assembled on the platform 1 for clamping the pipes 22. (The pipes 22 described herein refer to pipe bundles stacked by multiple layers of pipes 22.) The first limiting pieces 2, the second limiting pieces 3 and the platform 1 constitute the pipe storage space.

[0034] Further, the platform 1 is a rectangular structure formed by welding multiple profiles. Figure 3 As shown in the figure, the first limiting pieces 2 and the second limiting pieces 3 both extend along the vertical direction perpendicular to the platform 1, and the first limiting pieces 2 and the second limiting pieces 3 are separately arranged on both sides of the pipe bundle to limit the pipe bundle. According to the actual length of the pipes 22, a corresponding number of first limiting pieces 2 and second limiting pieces 3 are arranged in each pipe storage space. In general, one first limiting piece 2 and one second limiting piece 3 are arranged at the left and right ends of the platform 1, that is, two first limiting pieces 2 and two second limiting pieces 3 are arranged in each pipe storage space. The center line of the two first limiting pieces 2 is parallel to the axis of the pipes 22 on the platform 1, and similarly, the center line of the two second limiting pieces 3 is also parallel to the axis of the pipes 22 on the platform 1.

[0035] The first limiting pieces 2 and the second limiting pieces 3 can be square steel, round steel or other columnar structures.

[0036] More specifically, the bin body of the embodiment has two pipe storage spaces. That is, the platform 1 of the embodiment is provided with four first limiting pieces 2 and four second limiting pieces 3, and the specific distribution positions are as shown in the figure. Figures 3 to 5The first limiting members 2 are distributed on the front and back sides of the platform 1, two on each side, and the two first limiting members 2 on the front side are rotatably assembled on the platform 1 through the rotating plate seat 4 and can be rotated from a vertical state to a horizontal state; the two first limiting members 2 on the back side are fixed on the platform 1 and vertically extend upward. When the two first limiting members 2 on the front side are in the horizontal state, the staff can input the material pipe 22 onto the platform 1 from the front side; when the two first limiting members 2 are in the vertical state, the first limiting members 2 can cooperate with the second limiting members 3 to clamp and limit the material pipe 22 stored on the platform 1.

[0037] The four second limiting members 3 are round steel and are fixed on the platform 1 through the guide rod frame 5 and are always in a vertical state. When it is necessary to input the material pipe 22 onto the platform 1, the second limiting members 3 can be temporarily removed to facilitate the staff to input the material pipe 22 into the material pipe storage space on the back side.

[0038] The hosting assembly 6 is used to timely form a material pipe 22 supporting inclined surface at the bottom of the material pipe storage space. (Here, timely means when the lowermost material pipe 22 is grabbed.) As shown in Figure 3 , at least two hosting assemblies 6 are assembled on the silo body corresponding to each material pipe storage space, and all the hosting assemblies 6 corresponding to the same material pipe storage space are distributed along the axial direction of the material pipe 22 in the material pipe storage space. In this embodiment, two hosting assemblies 6 are assembled at the bottom of each material pipe storage space, and the two hosting assemblies 6 are separately arranged at the left and right ends of the platform 1 of the material pipe 22 body.

[0039] Specifically, each hosting assembly 6 includes a cooperating hosting plate 7 and a driving member. The hosting plate 7 is arranged along the width direction of the material pipe storage space and is a rectangular plate, and one end of the rectangular plate is connected to the silo body as a connecting end through a shaft pin 8, and the other end is an active end. As shown in Figure 3 , the active end of the rectangular plate is assembled with a rotating member 9. In this embodiment, the rotating member 9 is a bearing. The driving member is arranged directly below the active end of the rectangular plate and includes a gas cylinder 11 fixed on the silo body through a gas cylinder fixed plate 10, and the output end of the gas cylinder 11 extends vertically upward. When the output end of the driving member is retracted, the active end of the hosting plate 7 is placed on the driving member, and the hosting plate 7 is in a horizontal state, as shown in Figure 3 , the active end of the hosting plate 7 is placed on the top end of the gas cylinder fixed plate 10, and the rotating member 9 of the hosting plate 7 contacts the output end of the gas cylinder 11; as shown in Figure 5 , when the output end of the driving member is extended, the active end of the hosting plate 7 is lifted up, and the hosting plate 7 is in an inclined state as a whole.

[0040] Need to be supplemented, according to the circumstances, the hosting board 7 can also be set as a flat board with a larger area, and the connection mode with the silo body remains unchanged. The flat board can form a slope independently at the bottom of the tube storage space, without the need for multiple cooperation, so in this case, only one tube hosting assembly 6 needs to be assembled at the bottom of each tube storage space.

[0041] The above-mentioned tube storage silo 12 disclosed in the embodiment is generally used in the following manner: the output end of the driving member is in a retracted state, the hosting board 7 is in a horizontal state and located below the tube storage space, as shown in Figure 3 When the lowermost tube 22 in the tube storage space is taken out, the output end of the driving member is extended, the movable end of the hosting board 7 is lifted up, as shown in Figure 5 The hosting board 7 is in an inclined state (the inclination angle is generally 12°), and the lowermost tube 22 is caused to slide along the slope under the action of gravity to one side, so as to realize the positioning of the lowermost tube 22 and ensure that the transfer assembly 20 accurately identifies and grasps each tube 22 in the lowermost layer.

[0042] The embodiment further discloses a tube supply mechanism 19 for lifting the tube 22 to a certain height for subsequent conveying work. As shown in Figure 7 The tube supply mechanism 19 includes the tube storage silo 12 and a lifting assembly 13, wherein the tube storage silo 12 adopts the structure as described above. The lifting assembly 13 includes a stand column 14, a driving motor 15, a ball screw 16 and a nut 17. The stand column 14 is vertically fixed; the driving motor 15 is fixed on the stand column 14, generally at the bottom of the stand column 14, and can also be adjusted to the top or other positions according to the circumstances; the ball screw 16 is rotatably assembled on the stand column 14 and arranged along the height direction of the stand column 14; and the nut 17 is assembled on the ball screw 16 and connected with the platform 1 in the tube storage silo 12 through an angle iron.

[0043] Further, the output end of the driving motor 15 is connected with the ball screw through a speed reducer 18. In work, the driving motor 15 drives the ball screw to rotate, so that the nut 17 moves on the ball screw 16, and then the tube storage silo 12 as a whole is lifted and lowered through the nut 17.

[0044] The embodiment further discloses an automatic tube feeding machine of a bottle making machine, which is basically the same as the prior art, except that the tube supply mechanism 19 as described above is adopted. Specifically, as shown in Figure 8 The automatic tube feeding machine of the bottle making machine includes the transfer and tube inserting assembly and the tube supply mechanism 19 as described above, wherein the transfer and tube inserting assembly is the prior art.

[0045] The specific structure of the transfer cannula assembly is not described any more, and only the cooperation between the components is simply described: the pipe taking position of the transfer assembly 20 in the transfer cannula assembly corresponds to the output port of the pipe 22 of the pipe supply mechanism 19, the pipe discharging position of the transfer assembly 20 in the transfer cannula assembly corresponds to the pipe receiving position of the cannula applicator 21 in the transfer cannula assembly, and the cannula applying position of the cannula applicator 21 in the transfer cannula assembly corresponds to the input port of the pipe 22 on the gripper disc of the bottle making machine.

[0046] It should be noted that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments, or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
