Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated part production, in particular to a rollover demoulding device and a prefabricated part production line. Background Art

[0002] There are many advantages to realizing a batch and multi-category production line for prefabricated parts. For example, it can selectively produce according to different production needs within an effective space, and can effectively reduce the investment cost of equipment. In the field of railway transportation, many types of prefabricated parts are required and the quantity is large. For example, laying railways requires sleepers and some other small prefabricated parts (such as cover plates, fences, square bricks, etc.), which are not only of many types but also used in large quantities. How to develop a production line that can meet the needs of a variety of prefabricated parts is a technical problem that needs to be solved urgently by those skilled in the art.

[0003] Rollover demoulding equipment is an important component of prefabricated parts production lines. Existing rollover demoulding equipment for prefabricated parts often requires manual intervention, resulting in low demoulding efficiency and difficulty meeting the needs of batch production and multi-variety prefabricated parts production lines. Utility Model Content

[0004] The purpose of this application is to at least realize the flip demoulding of prefabricated parts, reduce human intervention, and better meet the needs of automated and batch demoulding and production of prefabricated parts.

[0078] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0079] The following combination Figures 1 to 11 The invention introduces the rollover demoulding equipment and the prefabricated parts production line provided by the invention.

[0080] The flip demolding device provided in the present application includes a first end wall 1, a second end wall 2, a first conveying unit, and a second conveying unit 4. The first end wall 1 is provided with a first opening 11 extending therethrough; the second end wall 2 is opposite the first end wall 1 and is provided with a second opening 21 extending therethrough, with the second opening 21 facing the first opening 11. The first conveying unit is located between the first end wall 1 and the second end wall 2, with the conveying path of the first conveying unit extending from the first opening 11 to the second opening 21. By positioning the first conveying unit between the first end wall 1 and the second end wall 2 and extending the conveying path of the first conveying unit from the first opening 11 to the second opening 21, the first conveying unit can transfer undemolded preforms from one of the first opening 11 and the second opening 21 to the flipping station of the flip demolding device, and can transfer demolded molds or the mold base 100 mounted thereon out of the flip demolding device from the other of the first opening 11 and the second opening 21.

[0081] like Figures 1 to 3 As shown, the second conveying unit 4 is connected to the first end wall 1 and the second end wall 2 respectively and is located between the first end wall 1 and the second end wall 2. Figure 10 As shown, the second conveying unit 4 includes a conveying assembly 41 facing the first conveying unit, and the conveying assembly 41 is configured to be able to move toward or away from the first conveying unit as a whole. Figures 1 to 3As shown, the second conveying unit 4 and the first conveying unit are respectively located on opposite sides of the conveying path of the first conveying unit. The conveying path of the conveying component 41 is toward one side of the flip demoulding device. In a specific implementation, it is preferred that the conveying path of the conveying component 41 is perpendicular to the conveying path of the first conveying unit. In the present application, the flip demoulding device includes a second conveying unit 4, and the second conveying unit 4 includes a conveying component 41 facing the first conveying unit, and the conveying path of the conveying component 41 is perpendicular to the conveying path of the first conveying unit. Then, the conveying component 41 can receive the demoulded preforms, and can transport the demoulded preforms to a position away from the flip demoulding device through the conveying component 41 to prepare for the next demoulding.

[0082] The present application arranges the conveyor assembly 41 to face the first conveyor unit and to be able to move toward or away from the first conveyor unit, thereby adjusting the position of the conveyor assembly 41 according to the actual working conditions of the flip demolding equipment. Specifically, the conveyor assembly can be moved to an appropriate position toward the first conveyor unit before flip demolding, so that during the flipping and demolding process, it can better receive the preforms that have been released from the mold, effectively preventing the preforms from slipping out of the mold and falling from a high position during the flipping process, and shortening the distance the preforms fall during the demolding process, thereby better ensuring the quality and yield rate of the preform products. At the same time, it can reduce the dynamic load generated by the preforms during the demolding process, thereby better improving the working conditions of the conveyor assembly 41 and reducing the maintenance costs of the equipment.

[0083] During specific operation, the flip demoulding device has a first state and a second state. In the first state, the first conveying unit is located directly above the second conveying unit 4 (eg Figure 1 As shown in the figure), in the second state, the second conveying unit 4 is located directly above the first conveying unit (not shown in the figure).

[0084] It should be noted that the structural forms of the first end wall 1 and the second end wall 2 of the present application are not specifically limited, and they can be any end wall that meets the installation and load requirements. Figures 1 to 3 and Figure 5 As shown, the first end wall 1 is disc-shaped as a whole, and a first circular raceway 12 is provided on the circular outer edge of the first end wall 1; the second end wall 2 is also disc-shaped as a whole, and a second circular raceway 22 is provided on the circular outer edge of the second end wall 2.

[0085] In order to enable the flip demoulding device to have a first state and a second state, as Figures 1 to 3 and Figure 5 and Figure 6As shown, the flip demolding device further includes two first support wheel assemblies 81, and the two first support wheels 811 are respectively located on both sides below the first circular raceway 12. Each first support wheel assembly 81 includes a first support wheel 811, and the two first support wheels 811 support the first circular raceway 12. The flip demolding device also includes two second support wheel assemblies 82, and the two second support wheel assemblies 82 are respectively located on both sides below the second circular raceway 22. Each second support wheel assembly 82 includes a second support wheel 821, and the two second support wheels 821 support the second circular raceway 22.

[0086] In order to enable the flip demoulding device to flip, the flip demoulding device further includes a fourth drive motor 83, so that at least one of the first support wheel assembly 81 and the second support wheel assembly 82 can be connected to the fourth drive motor 83. Figure 3 As shown, the fourth drive motor 83 is further driveably connected to a second support wheel assembly 82. During operation, the fourth drive motor 83 drives the first support wheel 811 to rotate the first end wall 1 and the second end wall 2, thereby enabling the flip demolding device to assume the first and second states. In practice, two, three, or four of the first support wheel assemblies 81 and the second support wheel assemblies 82 can be selectively driveably connected to a fourth drive motor 83.

Figures 1 to 3 As shown, the first opening 11 and the second opening 21 are both arranged in a square shape.

[0091] It should be noted that the "transfer path of the first conveyor unit" in this application refers to the path along which the first conveyor unit transports the mold or the mold table 100 on which the mold is mounted. Similarly, the "transfer path of the conveyor assembly" in this application refers to the path along which the conveyor assembly 41 transports the demolded preforms. In practice, the conveyor path of the first conveyor unit and the conveyor path of the conveyor assembly 41 are preferably located on parallel surfaces.

[0092] In some preferred embodiments of the present application, the second conveyor unit 4 further includes a mounting frame 42 and a push-pull device 43.

[0095] As some preferred embodiments of the present application, Figure 10 As shown, the conveying component 41 also includes a base frame 411 and a chain-type conveying component 412. The base frame 411 is generally plate-shaped and is connected to the mounting frame 42 via a push-pull device 43. Multiple chain-type conveying components 412 are installed on the base frame 411 at intervals along the conveying direction of the first conveying unit, and the transmission direction of each chain-type conveying component 412 is skewed and perpendicular to the conveying direction of the first conveying unit.

[0096] In this application, the structure of the base frame 411 is not specifically limited, and it can be any structure that can meet the installation requirements of the chain conveyor assembly 412. Figure 10 As shown, the base frame 411 is generally flat, and a plurality of chain conveyor assemblies 412 are installed on the base frame 411 at intervals along the conveying direction of the first conveyor unit. It should be noted that the spacing between adjacent chain conveyor assemblies 412 should be set according to the size of the preforms being transported to prevent preforms from becoming stuck between adjacent chain conveyor assemblies 412. Furthermore, there is no specific limit on the number of chain conveyor assemblies 412 on the base frame 411.

[0097] The present application comprises a conveying unit comprising a base frame 411 and a chain conveying assembly 412, and the chain conveying assembly 412 is installed on the base frame 411 at intervals along the conveying direction of the first conveying unit. With the help of the plate-shaped base frame, the load-bearing requirements of the preforms, especially those of small preforms, can be better met. Furthermore, the chain conveying assembly 412 can better meet the conveying requirements of small preforms, effectively preventing small preforms from slipping during conveyance, and making the conveyance of preforms after demolding more reliable.

Some adjacent driving sprockets 4121 are sleeved on the first transmission shaft 4124, and the first transmission shaft 4124 is transmission-connected to the first drive motor 4123; the remaining adjacent driving sprockets 4121 are sleeved on the second transmission shaft 4126, and the second transmission shaft 4126 is transmission-connected to the second drive motor 4125. For example Figure 10 As shown, the axes of the first transmission shaft 4124 and the second transmission shaft 4126 are both parallel to the transmission direction of the first transmission unit. In a specific implementation, the first drive motor 4123 and the second drive motor 4125 are preferably synchronized. Specifically, the first drive motor 4123 and the second drive motor 4125 can be controlled with the assistance of an encoder, or with the assistance of a PID controller or a PLC controller. Alternatively, the first drive motor 4123 and the second drive motor 4125 can be both servo motors and controlled by a servo controller to maximize synchronization between the first drive motor 4123 and the second drive motor 4125.

[0100] The present application enables some adjacent driving sprockets 4121 to be sleeved on the first transmission shaft 4124, and the first transmission shaft 4124 is driven by the first drive motor 4123. Thus, under the action of the first transmission shaft 4124, the synchronization of the multiple chain-type transmission assemblies 412 connected to the first transmission shaft 4124 can be effectively ensured, thereby achieving a better transmission effect. Similarly, the remaining adjacent driving sprockets 4121 are sleeved on the second transmission shaft 4126, and the second transmission shaft 4126 is driven by the second drive motor 4125. Thus, under the action of the second transmission shaft 4126, the synchronization of the multiple chain-type transmission assemblies 412 connected to the second transmission shaft 4126 can also be ensured.

The first conveyor line 91 is located upstream of the flip demoulding device 92 and extends from the upstream station of the flip demoulding device 92 to the first opening 11 of the flip demoulding device 92.

[0123] It should be noted that the upstream portion of the flip demolding device 92 described herein is described with reference to the prefabricated production process. In practice, the first conveyor line 91 is used to transport undemolded rail sleepers and undemolded small prefabricated parts. Furthermore, it should be noted that the upstream portion of the flip demolding device 92 described herein can optionally be a prefabricated curing station. In practice, the first conveyor line 91 can optionally be a roller-type conveyor line.

[0124] For example Figure 11As shown, the second conveyor line 93 is located on one side of the flip demolding device 92, with the first end of the second conveyor line 93 opposite the conveyor assembly 41. The second conveyor line 93 is located in a position to receive the small preforms conveyed by the conveyor assembly 41, and the second end of the second conveyor line 93 extends to the small preform palletizing station 94. During operation, the flip demolding device 92 flips and demolds the small preforms, causing them to fall onto the conveyor assembly 41. The conveyor assembly 41 transfers the demolded small preforms to the second conveyor line 93, which then transfers them to the small preform palletizing station 94, where they are further palletized manually or by a palletizing robot. In practice, the second conveyor line 93 can optionally be a chain conveyor line or a roller conveyor line.

The sleeper de-molding device 97 is configured to de-mold the sleepers and transfer the sleeper molds, as well as transfer the small preform molds or the mold table 100 mounted with the small preform molds to the fifth conveyor line 98.

[0126] During specific operation, when the product produced by the preform production line is a small preform, the undemolded small preform is conveyed to the first conveying unit via the first conveyor line 91, and the position of the conveying component 41 is adjusted so that the conveying component 41 moves to the set position toward the small preform mold carried by the first conveying unit or the mold table 100 on which the small preform mold is fixed. After the position of the conveying component 41 is adjusted, the flip demoulding device 92 is in the first state and demoulded, and then the small preform mold or the mold table 100 carrying the small preform mold is flipped, and then the flip demoulding device 92 is in the second state, and the small preform mold or the mold table 100 carrying the small preform mold is further transferred to the third conveyor line 95 via the first conveying unit, and then the small preform mold or the mold table 100 carrying the small preform mold is further transferred to the downstream station of the flip demoulding device 92 via the third conveyor line 95. Specifically, Figure 11 As shown, the small preform mold or the mold table 100 carrying the small preform mold is transferred to the sleeper flipping and demolding station via the third conveyor line 95, and then the small preform mold or the mold table 100 carrying the small preform mold is transferred to the fifth conveyor line 98 via the sleeper flipping and demolding device 97. The small preform mold or the mold table 100 carrying the small preform mold is further transferred to the mold cleaning station via the fifth conveyor line 98.

[0127] When the prefabricated parts production line produces sleepers, the demolding device 92 is maintained in the second state, and the undemolded sleepers are sequentially conveyed via the first conveyor line 91, the first transfer unit, and the third conveyor line 95 to the sleeper demolding device 97. The sleepers are then demolded by the sleeper demolding device 97, and the demolded sleepers are transferred to the sleeper stacking station 99 via the fourth conveyor line 96, where they are stacked by the sleeper stacking device. Under the action of the sleeper demolding device 97, the sleeper mold is transferred to the fifth conveyor line 98, and then transferred to a downstream station of the sleeper demolding device 97 via the fifth conveyor line 98. In a specific implementation, the downstream station of the sleeper demolding device 97 can optionally be a mold cleaning station.

[0128] As some preferred embodiments under the aforementioned embodiments, Figure 11 As shown, the sleeper flip demoulding device 97 includes a load beam 971 and a lifting trolley 972, and the two load beams 971 are arranged side by side.
