Description

A prefabricated component production line with temporary storage function

technical field

The invention relates to a prefabricated component production line with a temporary storage function, belonging to the technical field of prefabricated component production.

Background technique

The feature of the assembly line production method of prefabricated components is that the table mold/steel trolley (that is, the working platform) flows to the corresponding station of each process through the conveying system of the production line with the process sequence; the operator and specific work of each station Relatively fixed, for example, table mold cleaning, sidewall mold installation, pre-embedded parts, reinforcement arrangement, concrete pouring, vibrating and other operations are operated by relatively fixed people and equipment in fixed positions. This type of production process can reduce labor intensity, improve production efficiency, and save labor. Therefore, domestic prefabricated component manufacturers currently use assembly line production for prefabricated exterior wall panels and interior wall panels.

The production process of existing prefabricated components generally includes: cleaning molds, spraying and marking, installing molds, arranging steel bars/embedded parts, pouring vibrating concrete, leveling concrete, pre-curing, grinding, curing kiln curing, demoulding , hoisting, etc.

In these processes, the time rhythm of the operation (processing) of the pouring and vibrating concrete, leveling concrete, pre-curing, grinding, curing kiln curing, demoulding, and hoisting stations is roughly fixed, and will not be affected by the form, size and other factors of the prefabricated components. produce larger changes. However, the operation time of installing molds and arranging steel bars/embedded parts will vary greatly depending on the form and size of prefabricated components. Especially for customized parts customized for specific construction projects, their unconventional shapes often Extended operating time for installing molds and arranging rebar/embedded parts. As shown in Figure 1, the production process of a typical prefabricated component production line in the prior art is: the prefabricated component that has completed the entire production process is demolded at the demolding station (removal of the sidewall mold), and then the prefabricated component is hoisted. , the prefabricated components are transferred to the finished product warehouse, and the remaining table molds are transferred along the first assembly line, and the mold cleaning, mold loading, reinforcement arrangement, and pre-embedded parts are carried out in turn. During these operations, the table mold can be removed from The first assembly line is transferred to the second assembly line through the table-frying mechanism. After the above operations are completed, the background mold enters the placing station for concrete pouring and vibrating. After some post-casting treatment, it enters the curing kiln for curing. The cured table mold Come to the demolding station to complete a production cycle.

If the existing production line only produces a single prefabricated component product, it can roughly ensure that each production process is in a controllable state, and the production plan can be arranged according to the average number of prefabricated components produced in 24 hours, and the production rhythm is not easily disrupted. However, when different types of prefabricated components need to be produced at the same time, especially personalized customized parts, it is difficult to coordinate the operation time of installing molds and arranging steel bars/embedded parts. For example, personalized customized parts are installed in molds. It takes several times more time than conventional prefabricated components, which will lead to the disruption of the subsequent conventional prefabricated components production cycle of personalized customized parts, and the production line will be congested and reduce the production line capacity if the production line is too slow.

SUMMARY OF THE INVENTION

In order to overcome the problems existing in the prior art, the present invention provides a prefabricated component production line with a temporary storage function, and the specific technical scheme is as follows.

A prefabricated component production line with a temporary storage function is characterized in that it includes a first assembly line, a second assembly line, a third assembly line, a fourth assembly line, a table mold ferry mechanism, a curing kiln and a table mold temporary storage unit, the first assembly line A distributing station is arranged on the assembly line, a demoulding station is arranged on the second assembly line, and both ends of the first assembly line are respectively connected with the curing kiln and the temporary storage unit, and the second assembly line One end is connected with the curing kiln, and the other end is connected with one end of the third assembly line; the third assembly line is provided with at least one of a mold cleaning station, a mold loading station and a reinforcement station. The fourth assembly line is provided with at least one of a mold clearing station, a mold loading station and a reinforcement station; one end of the fourth assembly line is connected with the stage touch temporary storage unit, and the other end is connected with the third assembly line The other end of the mold is connected by the table mold ferry mechanism; the table mold temporary storage unit is used to temporarily store the table mold after the reinforcement operation.

Compared with the prior art, the above-mentioned technical solution of the present application adds a mold temporary storage unit, so that the production cycle process of the prefabricated component can be roughly divided into two areas with the mold temporary storage unit as the limit, namely, the production cycle is not fixed area and Production takt fixed area. The specific production process is roughly as follows: after the table molds used to produce prefabricated components are cleaned on the third assembly line and the fourth assembly line in turn, after the operation of the mold cleaning, the installation of the sidewall molds, the arrangement of the steel bars, and the placement of the embedded parts, the fourth assembly line is completed. Transfer to the table form temporary storage unit for temporary storage; due to the different types and sizes of prefabricated components, the above operations have great differences in time for different prefabricated components. The time required for the pre-embedding of the embedded parts can be considered as uncertain, that is, the production tact in this part of the production line is uncertain. The table mold in the table mold temporary storage unit can transfer a table mold to the first assembly line according to a certain time rhythm (for example, 15 minutes). Then, after troweling, grinding, resting, roughening and other post-processing procedures, it enters the curing kiln for curing, and the curing background mold and its prefabricated components are transferred to the second assembly line, and the sidewall mold removal and demoulding are completed on the second assembly line. Operation, the table mold used to produce the prefabricated component is demolded at the demolding station of the second assembly line (the prefabricated component is lifted off the table mold) and transferred to the third assembly line to complete a production cycle; the first assembly line, maintenance The operation time of the kiln and the second assembly line is almost not limited by the type and size of prefabricated components, and prefabricated components of various types and sizes can be produced on the first assembly line and the second assembly line according to the set time interval, that is, the first assembly line and the second assembly line. The area formed by the first line, the curing kiln and the second line can be called the production takt fixed area. The table pattern temporary storage unit is used to accumulatively store a certain amount of table molds, which can ensure that the table molds are provided for the first assembly line uninterruptedly for 24 hours, so as to ensure that the demolding station of the second assembly line is in accordance with the set tempo (time). Interval) off-line prefabricated components are completely unaffected by the ever-changing types and sizes of prefabricated components, so that the operation processes with unfixed production rhythms are all located upstream of the table mold temporary storage unit. In this case, it is only necessary to increase production. The production capacity in the variable rhythm area ensures that there are enough table molds in the temporary storage unit for prefabricated components to be continuously produced. The temporary storage unit of the table mold plays the role of "buffering and storing water", and the adaptability of the production line is greatly improved, and the production of different types of customized prefabricated components will not cause the production line to block or reduce efficiency.

There are always enough tables in the table staging unit. This setting can reduce the number of personnel in three shifts on the production line, and a large number of workers required for the mold cleaning station, the mold installation station and the reinforcement station can only work during the day, that is, the table mold temporary storage unit can be guaranteed when off work during the day. There are enough table molds required for night production of the production line, and the table molds in the table mold temporary storage unit are continuously transferred to the first assembly line according to a fixed rhythm, so that only a small amount needs to be arranged in the first assembly line and the second assembly line at night. 24-hour uninterrupted production of the production line can be achieved with only 100 staff members, and there is no need for staff in all positions to work three shifts.

Further, the third assembly line and the fourth assembly line are both provided with two or more, and the third assembly line and the fourth assembly line are arranged at intervals, and a third assembly line and a fourth assembly line are formed. In one group, one end of the third pipeline and the fourth pipeline in a group that is far away from the stage-mode temporary storage unit is connected through the stage-mode temporary storage unit. In this way, the number of mold cleaning stations, mold loading stations and reinforcement stations can be increased, and the table molds of multiple third and fourth assembly lines can be transferred to each other, which improves the production capacity in areas where the production rhythm is not fixed. There are always enough tables in the table staging unit. In this way, part of the third assembly line and the fourth assembly line can be dedicated to the production of complex, special-shaped or customized prefabricated components, even if the production efficiency at this stage is low, it will not block the entire production line or reduce the output efficiency of the entire production line .

Further, the first assembly line is sequentially provided with a fabricating station, a leveling station and a post-processing station.
